The ODS special conference offers an excellent forum for exchanging information on the status, advances, and future directions in the field of industrial optical devices and systems. Formerly, the main topic of this conference was optical data storage. However, competition with hard disk drives and solid state drives, as well as the growth of storage in the cloud, made it unclear what the future optical data storage system might look like. Therefore, the scope of the conference was extended to “Industrial Optical Devices and Systems” in 2018, and the new scope was brought to the forefront in 2019. To further activate the ODS conference, the new scope will be continuously highlighted in 2021.

Currently, optics research and development community in industry is seeking for new applications of the technologies developed for optical data storage in the past. The possibility of applications of optical technologies to emerging industrial domains such as automotive, IoT, big data, healthcare, security, etc. will be the main focus at this conference. A variety of optical technologies such as LiDARs, VR/AR, intelligent lighting, advanced cameras, etc. are involved in the above applications. Of course, new developments in technologies for future optical data storage systems such as holographic data storage, nano-photonics, etc. will also be discussed. Contributions in a variety of areas within the new scope of ODS are strongly encouraged.

Papers are solicited in the following and related areas: ;

Optical time-domain reflectometers are typically used for either short-reach or long-haul applications, but not both, due to their trade-off with spatial resolution and dynamic range. Some designs can achieve high spatial resolution over long distances, but they are not practical for industry use due to their requirement for extra hardware which increases the cost, form-factor, and complexity of the system. A reconfigurable optical time-domain reflectometer is proposed that goes beyond the state-of-the-art designs due to its capability of being efficiently integrated with optical transceivers with little to no hardware modification. The reconfigurable design enables a high spatial resolution to be achieved in addition to attenuation measuring capability.

Three-dimensional (3D) plasmonic sensors have been developed using the reversal nanoimprint technology. Using this technology, plasmonic sensors with additional levels of metals and asymmetrical profiles were optimized to achieve high sensitivity for biomolecule detection. Combining the unique designs of these 3D nanostructures, the plasmonic sensors have high performance as the devices combined the hybrid coupling effect of localized surface plasmon resonance, Fano resonance, and Fabry-Perot cavity modes to achieve sharp resonance peaks with large resonance peak shifts. Applications of these high performance nanoplasmonic sensors to biosensing will be presented.

We are presenting a way to implement a curved waveguide as the combiner element for heads up display (HUD) or augmented reality (AR) glasses. Most of waveguide implementation for combiner are straight pieces of glass because the image propagation does not suffer from any aberration when traveling along their length. However, this type of combiner does integrate seamlessly in front of the viewer eyes and a curved optics would be much more appealing. Proof is no commercial pair of glasses use flat lenses, they are all curved. The problem we solved is how to correct the aberrations induced by the curved surfaces of the waveguide and display a correct image to the viewer. In this presentation we will detail the different possible geometries for the waveguide and the compensations that are required from the injection and extraction holograms.

We have previously developed and demonstrated the multi-tone continuous wave (MTCW) lidar for static and slow-moving targets that eliminates any form of sweeping. The MTCW lidar operates by employing amplitude modulation via multiple radio frequencies (RF) and coherent detection. In this work, we present a theoretical and experimental study on MTCW lidar that can detect the range and velocity of objects with arbitrary velocities. The experiments demonstrate that the phase and frequency of the Doppler-shifted fixed RF tones can be used to extract the range and velocity information in a single shot measurement. We show that a <±1cm resolution in the ranging, limited by the temporal resolution of the detection system, and a 0.4cm/s speed resolution that is limited by the linewidth of the laser and frequency resolution of the detection system are achievable.

The optical implementation of neural networks has great advantages in power consumption and computation speed. However, the existed optical implementations follow the conventional real-valued algorithms that are designed for electronic devices and thus forfeit the unique advantage of optical platforms (i.e., their ability to process information under complex arithmetic). The complex-valued neural networks are advantageous to their real-valued counterparts by offering rich representation space, fast convergence, and strong generalizations. We propose and experimentally realize an optical neural network that executes complex-valued neural networks. High accuracy and strong learning capability are achieved. On the other hand, we demonstrate a gradient-free and physics-agnostic Genetic Algorithm-based training of the optical neural network-on-chip. Our results present a promising avenue towards deep complex networks with smaller chip sizes and stronger performance.

A concept of Texas Instrument (TI)-Phase-only Spatial Light Modulator (PLM) is reported which utilizing the dynamic piston motion of PLM pixels to form a discretized blazed grating. By fully manipulating the piston motion of pixels and increasing the discretization level of the quasi-blazed grating, the Diffraction Efficiency (DE) can achieve close to 99% in theory, which makes PLM ideal for beam steering functionality combining with its MEMS-based high refresh rate and large aperture. The DE of the discretized blazed grating is proven to have 86% with 633 nm monochromatic light incident at 25° with 16 discretization levels by the RCWA algorithm. Furthermore, additional factors which lead to the degradation of diffraction efficiency are also analyzed.

Nanoscale optical writing enables high-density optical data storage. However, current techniques usually require high laser beam intensity with high energy consumption and short device lifetime. Upconversion nanoparticles (UCNPs) have shown great potential for high-density optical data storage due to their exceptional luminescence emissions. In addition, UCNPs have enabled low-power STED microscopy. We show that UCNPs can induce the reduction of graphene oxide (GO) at the nanoscale. Dual-beam super-resolution irradiation was used to write features in UCNP-conjugated GO with lateral feature size at the nanoscale and inhibition intensity of <15 MW/cm^2. This approach might offers a convenient and energy-efficient solution for the storage demands in the Data Age.

Phase retrieval is the key technique in phase-modulated holographic storage. In this paper, a deep convolutional neural network is proposed to directly retrieve phase data. Compared with the traditional non-interferometric phase retrieval method, this method has the advantages of fast retrieval speed and high reconstruction accuracy. In this paper, the influence of intensity image noise on retrieval results under different retrieved conditions is researched and analyzed. By establishing a simulation system that is in strict agreement with real experiments, the lensless spatial diffraction images are generated. By adding different proportions of random noise into the intensity images we get the training dataset. The convolutional neural network is trained by a training dataset and tested by a new noisy test dataset. Experimental results show that the phase retrieval method based on deep learning has a high tolerance for systematic errors and strong anti-noise performance.

To increase the capacity of optical disc systems, suppression of noise signal from recording media is important. The media noise is generated during the manufacturing and/or recording process. It may have a different character from the recorded information because of the difference between the processes to create them. Several readout channels such as divided photo detectors, multi-wavelength illumination and different optical parameters enable us to derive various characteristics of signals from readout media. Some methods and calculated results to suppress the medium noise by using such multimodal readout will be discussed in this paper.

Heat-assisted magnetic recording (HAMR) is a promising technology for achieving more than 10 Tb/inch^2 recording density. A near-field transducer (NFT), which forms a small light spot on a recording medium, is necessary in HAMR. The authors have proposed a novel device, in which a metal nano-antenna as an NFT is attached to a semiconductor ring resonator as a light source. How to excite a desired eigenmode selectively among multiple eigenmodes in the ring resonator is important to make this device efficient and stable. For this purpose, some ideas on the improvement of the structure of the device will be discussed.

Based on polarization holography theory, the plane bifocal vector lens is studied. In previous studies, the bifocal vector lens were limited to cross-angle π/2 and bulk materials. However, when the two waves are orthogonal circularly polarized state, the plane bifocal vector lens can be realized, and the limitation of cross-angle π/2 and bulk materials can be broken. The lens produces corresponding focus output through the reading wave with different polarization states, which can be used for large-area optical element research.

A new scheme of advanced driving beam (ADB) module employing ultra-reliable Ce3+: YAG-based single crystal phosphor (SCP) for use in autonomous vehicles is demonstrated. The Ce3+: YAG-based SCP layers fabricated by high-temperature of 1,940°C exhibits excellent thermal stability. The ADB module consists of a Nichia blue LED with silicone-based phosphor, a digit mirror device (DMD), a projection optics system, and a blue laser auxiliary system. The high-beam pattern of the ADB is measured at a luminous intensity of 88,436 cd at 0°, 69,393 cd at ± 2.5°, and 42,942 cd at ± 5°, which well satisfies the ECE R112 class B regulation. The proposed high-performance ADB module with ultra-reliable Ce3+: YAG-based SCP layer is favorable as one of the promising ADB module candidates for use in the next-generation automobile headlight applications.
