ISAMU AKASAKI, special distinguished professor of Meijo University, and distinguished university professor and emeritus professor of Nagoya University, the pioneer of blue LEDs, and the Nobel Laureate in physics, passed away from pneumonia on Thursday, April 1, 2021 at the age of 92. He was always a real pioneer. He started nitride research in 1967. At that time, blue LED research was an undeveloped area. When he moved from Matsushita Giken Co., Ltd. to Nagoya University in 1981, almost no other organizations attempted to continue with the topic. At that time, the majority of researchers determined that it was very difficult to grow single crystals, and that realizing p-type GaN was impossible. Therefore, many abandoned GaN. According to him, his situation at that time was like “going alone in the wilderness.” Today, the wilderness pioneered by Professor Isamu Akasaki is now a prosperous and fruitful field where many researchers all over the world are gathering and bringing happiness to the people. He liked the term “Frontier Electronics.” In this presentation, in addition to his memorial, today’s frontier electronics will be discussed.
Inverse designed integrated photonics (Plenary Presentation)

Despite a great progress in photonics over the past few decades, we are nowhere near the level of integration and complexity in photonic systems that would be comparable to those of electronic circuits, which prevents use of photonics in many applications. This lag in integration scale is in big part a result of how we traditionally design photonics: by combining building blocks from a limited library of known designs, and by manual tuning a few parameters. Unfortunately, the resulting photonic circuits are very sensitive to errors in manufacturing and to environmental instabilities, bulky, and often inefficient. We show how a departure from this old fashioned approach can lead to optimal photonic designs that are much better than state of the art on many metrics (smaller, more efficient, more robust). This departure is enabled by development of inverse design approach and computer software which designs photonic systems by searching through all possible combinations of realistic parameters and geometries. We also show how this inverse design approach can enable new functionalities for photonics, including compact particle accelerators on chip which are 10 thousand times smaller than traditional accelerators, chip-to-chip on on-chip optical interconnects with error free terabit per second communication rates, and quantum technologies.

In this talk we will discuss how to engineer the dispersion relation of photonic platforms to provide robust propagation of classical and quantum states of light. In the first part, we will unveil how to leverage the interaction of nonlinearity with higher orders of dispersion to create novel types of solitons, wave packets that propagate unperturbed for long distances. These objects have advantageous energy-width scaling laws with respect to conventional nonlinear Schrodinger solitons and show promise for applications in ultrafast lasers and integrated frequency combs. Subsequently, we will cover recent developments in topological quantum photonics. Topological photonics studies topological phases of light and leverages the appearance of robust topological edge states. We will emphasize our experimental demonstration of nonlinearly generated and topologically protected photon pairs and path-entangled biphoton states in silicon waveguide arrays. Further, we will detail our latest experiments demonstrating entanglement between topologically distinct modes, highlighting topology as an entanglement degree of freedom.

The holographic optical element (HOE) plays an essential role in augmented reality optics as an image combiner that provides users by combining real and virtual scenes due to the advantages of transparency and high selectivity of light. However, an optical system using HOE has an issue in which aberrations such as astigmatism occur. Compensating for aberrations and securing a wide eye box and wide viewing angle remains as a challenge for AR optics to provide users a more convenient and immersive viewing experience. This paper reviews previous studies conducted to correct aberrations, expand the eye box, and broaden the viewing angle for AR optical systems, such as a head-up display and near-eye display.

The computer-generated hologram (CGH), as a promising technology for three-dimensional display, has attracted broad attentions in the past two decades. Since few display devices can modulate the amplitude and phase of the incident wavefront simultaneously, the complex amplitude holograms are converted or encoded to amplitude-only holograms or phase-only holograms (POH) for display. The approaches to obtain POHs include the Gerchberg-Saxton algorithm, the one-step phase retrieval method, the error diffusion method, the double phase method, the deep learning method, and so on. We would like to present the recent progresses in POH for display in our research group.

Computer-Generated Holography (CGH) promises to deliver genuine, high-quality visuals at any depth. We argue that combining CGH and perceptually guided graphics can soon lead to practical holographic display systems that deliver perceptually realistic images. We propose a new CGH method called metameric varifocal holograms. Our CGH method generates images only at a user's focus plane while displayed images are statistically correct and indistinguishable from actual targets across peripheral vision (metamers). Thus, a user observing our holograms is set to perceive a high quality visual at their gaze location. At the same time, the integrity of the image follows a statistically correct trend in the remaining peripheral parts. We demonstrate our differentiable CGH optimization pipeline on modern GPUs, and we support our findings with a display prototype. Our method will pave the way towards realistic visuals free from classical CGH problems, such as speckle noise or poor visual quality.

In this paper, we analyze the system light efficiency (SLE) of VR headsets from display to eye-box and image non-uniform caused by the imaging process of magnifying lens. Through the analysis results, the microcavity structure of the OLED display is optimized to suppress image non-uniformity, while maintaining a high SLE. Regarding the LCD-based VR system, a 2D patterned prism film is proposed to locally modulate the radiation pattern of the display, thereby breaking the trade-off between light collection efficiency and vignetting effect. The proposed optimization method provides useful guidelines for designing next-generation display devices for the VR system.

Autonomous cars should communicate with other road users such as visualizing its driving mode or that a pedestrian is recognized and the car will stop. Such displays must be sunlight readable and smoothly integrated into the front and rear of a car. We prototyped a mock-up for evaluation of LCDs, LEDs and e-paper regarding optical performance. We conducted a survey with subjects regarding display technology and content. RGB LED matrix displays are most suitable and can be integrated into the radiator grille and/or use the hidden display effect. Colored animated icons rates best, text should be rarely used.

Light field displays offer an unparalleled 3D experience, but suffer from poor image quality, low resolution and limited FOV. We show how a laser-lit backlight developed by VitreaLab, comprising a photonic chip which distributes light into an array of millions of tightly confined laser beams, overcomes these shortcomings. These beams illuminate, one-by-one, the subpixels of an LCD before hitting specially designed diffractive optical elements (DOEs) that steer the pixel-beams towards precise viewing positions. This design provides a continuous set of views, at a variable viewing distance, produces a 10x improvement in resolution compared to lenslet-based displays and features a FOV>90°.

To achieve user immersion experience and wearing comfort, AR/VR glass designer targeting general consumer market strives hard for larger FOV and smaller form factor. These ultimate goals cause challenges for mass production metrology due to geometrical conflicts and test cost inefficiency. Two imaging system designs are reviewed in this paper. Both resolve above practical issues of AR/VR glass optical resolution test by shifting the complexity of the lens design to a novel optical coupler. This coupler smartly remaps discrete angular field points onto a detector with minimum spatial gap. Proposed methodologies significantly decrease the metrology equipment cost for mass production.

Virtual reality (VR) systems bring fantastic immersive experiences to users in multiple fields. However, the performance of VR displays is still troubled by several factors, including inadequate resolution, noticeable chromatic aberration, and low optical efficiency. Pancharatnam-Berry phase optical element (PBOE) exhibits several advantages, such as high efficiency, simple fabrication process, compact, and lightweight, which is an excellent candidate for VR systems. We have demonstrated that by using three kinds of PBOEs, the above-mentioned problems can be solved satisfactorily. These ultrathin PBOEs will find promising applications in future VR systems.

A tunable liquid crystal (LC) polarization rotator that can rotate the polarization axis of linearly-polarized broadband light is achieved by using an asymmetrically-anchored negative LC cell. Interdigitated electrodes are used to apply an in-plane field to control the twist angle. The use of the asymmetrical anchoring in the LC cell enables continuous change of the twist angle by increasing the applied electric field. For uniform transmission, we used an LC that has negative dielectric anisotropy to avoid tilting of LC molecules by the vertical component of the electric field. We theoretically and experimentally confirmed that the fabricated LC cell could continuously change the twist angle and rotate the polarization axis of the linearly-polarized broadband incident light. We expect that this device will have applications in spectropolarimetry, optical communication, and medical imaging.

High radiance red-emitting light sources are required for several laser applications such as flying-spot-displays or high-resolution microscopy. As many of such applications are moving out of the lab into industrial environment there is a high demand for small sized, efficient and reliable laser sources, for which semiconductor lasers are preferred. We will present red-emitting tapered diode lasers at 635 nm which provide up to 1 W of optical power with a nearly diffraction limited beam. We demonstrate an operation of more than 2 000 h at a power level of 500 mW.

We introduce our recent works to remove the discrepancy between the perceived distance and optical distance of the images in optical-see-through (OST) augmented-reality (AR) near-to-eye displays (NEDs). The first one is a thin Maxwellian display which is implemented using a waveguide and a pin-mirror array holographic optical element (HOE) coupler. A dual-image-layer AR NED implemented using a polarization grating and a single physical waveguide is also introduced in the presentation. Our recent implementations of light field AR NED which uses a micro lens array to present 3D images, and holographic 3D AR NED are also introduced with experimental results.

The holographic waveguide-type AR display system using the liquid-crystalline MLA is proposed. The liquid-crystalline MLA has a small focal ratio, high fill factor, low driving voltage, and fast switching speed. According to the direction of an electrical polarizer, the 2D or 3D modes of the system are switched where the depth camera acquires the depth and color information of the real object. In the experiment, the proposed system has some common features like holographic waveguide-type AR display such as lightweight and thin size, and the observer can see the virtual 2D or 3D visualizations in the real-world environment.

The augmented reality (AR) market requires head-up displays (HUDs) with a wide field of view (FoV) along with a large eye-motion box (EMB) but at a low volume. To implement AR, we also need to provide the virtual image with 3D depth. It ensures viewers match projected information with real scenes without distraction and fatigue. In this study, we propose a low-volume HUD system with stereoscopy-based 3D images. To achieve this, we integrate a multi-view EMB formation unit (MV-EFU) into a pupil-replication-based waveguide system. Moreover, we demonstrate an approach to extend an FoV by varying parameters of the MV-EFU. Finally, we verify our approach with a full-color design with the FoV of 20° × 7° most suitable for automotive applications.

In this invited talk, we summarized our current results: a series of carbazole-imidazole derivatives with wide bandgap were utilized to be the host of high-efficiency organic light emitting diodes (OLEDs), which could be fluorescence, phosphorescence, and thermal activate delayed fluorescence (TADF), etc. Due to the wide bandgap properties, these hosts exhibited an efficient energy transfer with blue fluorescent emitters in singlet excitons to achieve the high efficiency. In particular, these hosts also exhibited a special behavior “long triplet diffusion” to benefit the triplet use in emission, especially goof for phosphorescent and TADF OLEDs. The hosts could delivery the triplet excitons near to the emitters and then energy transfer in the emitting layer to achieve the high efficiency. In addition, these hosts also had good molecular packing to benefit the light extraction of OLED and then showed the high external quantum efficiency.

Triplet-triplet annihilation (TTA) based OLED is the main stream for mass production with superior lifetime performances together with reasonable efficiency. Here, a bilayer emitting layer (EML) was employed to improve the lifetime of blue TTA-OLED. Compared to single-EML TTA-OLED, not only the external quantum efficiency of the bilayer OLED increased from 7.0% to 9.6%, but also the operation lifetime improved from 9.4 hr to 12.6 hr at T90 (the time required for luminance reduction to 90% of the initial luminance under a constant current density) with an initial luminance of 12500 cd m-2.

This talk covers thin-film devices based on amorphous oxide semiconductors (AOS) while discussing related physical mechanisms and potential applications, such as neuromorphic systems. Intentionally using a light-induced metastability mechanism of oxygen defects in AOSs, it is allowed to detect even visible lights, eluding to a persistent photoconductivity (PPC) as an optical memory action. So, this PPC phenomenon is naturally useful for AOS-based optical memory applications, e.g. optical synaptic transistors along with an electrical controllability of a recovery speed with gate pulse or bias. In this respect, AOSs can be promising materials for a low-cost transparent neuromorphic application.

Various free-form OLED platforms have been developed and their potential was demonstrated through actual bio-applications. For photobiomodulatoin (PBM), a sandwich-structured transfer free-form OLED (STOLED) that can be freely transferred to various materials has been developed. The STOLED was used to identify cell proliferation and migration effects up to 26 and 32%, respectively, and the effect of epidermis thickness increased by 39% in the skin equivalent model. For photodynamic therapy (PDT), an free-form device with low voltage and high radiant emittance (up to 100 mW/cm2) was developed through parallel-stacked OLED (PAOLED). A 24% reduction in melanoma cancer cell viability in a very short time (0.5h) was observed when using the PAOLED. Phototherapy that exceeds the current time and space limitations will permeate daily life through OLED-based platforms.

The flexible micro-LEDs are considered for diverse applications, such as wearable display. Although transparent plastics are usually utilized as the substrates or the top covers of the flexible devices, their low thermal conductivities are detrimental to the thermal dissipations of the devices, resulting in the shrinkage of lifetime and the degradation of the electrical performance. To investigate such issues in the flexible micro-LED, we integrated the thermal and electrical models for the reported micro-LEDs. The primary results showed that the flip-chip structure exhibits the lowest temperature of multiple quantum well, compared with those of the horizontal and the vertical structures.

MicroLEDs have a tremendous potential for future displays. However, there are several technical challenges to overcome prior to widespread deployment of MicroLEDs. One key hurdle is developing a process to release the dies from the sapphire growth wafer. Another is a process to transfer these to the display substrate with micron level precision and reliability. Laser processing offers several opportunities for MicroLED display production, such as Laser Lift-Off (LLO) to separate the finished MicroLEDs from the sapphire growth wafer and Laser Induced Forward Transfer (LIFT) to move the devices from a donor to the substrate. In this presentation, laser-based system solutions for the different manufacturing steps for MicroLEDs, will be presented. Integrated process control and monitoring is used to assure stable and reliable operation to ensure high throughput and low yield losses.

In this study, we incorporate phenethylammonium halide (PEAX, where X = Cl, Br, and I) during the perovskite quantum dots (PQD)/cellulose nanocrystals (CNC) film synthesis process. The phenethylammonium halide provides a halide-rich environment and a more significant quantum confinement effect to PQD in the CNC films. By combining the advantages of CNC and PEAX, stable light emission/conversion films with largely enhanced photoluminescence (PLQY) can be achieved. The PLQYs of CsPbBr1.5Cl1.5, CsPbBr3, and CsPbBr0.5I2.5 films with PEAX passivation can be improved more than 10 (from 1.2% to 10%), 3 (from 22% to 62%), and 6 (from 8% to 45%) times, respectively.

The previously proposed retinal projection type super multi-view HMD has a problem that the depth range of 3D images is limited to about 2 meters. To overcome this problem, we propose the binocular stereoscopic HMD pairing the previously proposed HMDs. The depth range of 3D images of the proposed HMD is expanded by using not only the accommodation of the human eye but also the convergence. In addition, the accommodation-convergence conflict is solved because the accommodation is correctly induced in the proposed HMD. Therefore, the proposed HMD can display natural 3D images in the expanded depth range.

We propose the 3D display with the fixed parallax barrier that enables the observation of high-quality 3D images in both portrait and landscape modes. We propose the method of designing the fixed parallax barrier that can be used in both portrait and landscape modes with low-crosstalk and without moiré, and propose the method for rendering stereo images corresponding to the screen orientation and the viewer’s position. We confirmed that the system can display high-quality 3D images with the crosstalk ratio of less than 4% in both portrait and landscape modes by using the prototype system.
