LIGENTEC delivers next-generation heater module for its All-Nitride process with Lumerical’s DEVICE Suite
LIGENTEC’s advanced heater module provides 4 times more thermo-optical tuning and improved stability for tunable ring resonators and Mach Zehnder Interferometer (MZI) than standard heaters in SiN. The newly available heater module is optimized for LIGENTEC’s all-nitride AN800 process with waveguides that offer low bending radii (< 0.005 dB for 10 turns of 50um radius), low coupling losses (< 1 dB/facet), low propagation losses (< 0.1 dB/cm) and high power handling (up to 10 W tested). Designed using Lumerical’s DEVICE Suite, LIGENTEC’s heater module is responsive and stable over an ultra-broad tuning range. For example, a ring resonator with a free spectral range (FSR) of 500 GHz (resonance separation of 4 nm) can be tuned by more than 4 nm operating at telecom wavelength range and thus covering a full tuning of the FSR. Similarly for MZIs, multiple pi-phase shifts are possible.

LIGENTEC designed their heater module with Lumerical’s DEVICE Suite, which performs multiphysics simulation of heat and electrical conduction, combined with photonics simulation, including relevant material models in each physical domain. It is an ideal platform for designing photonic integrated circuits (PICs) targeted for LIGENTEC’s All-Nitride (AN) process. “With its fast simulation performance and a high level of consistency with experimental data, Lumerical’s DEVICE Suite enabled LIGENTEC to optimize the performance of its heater module saving time and money,” says managing director Dr. Zervas. Lumerical’s simulators allowed for the import of measured data into its material models to maximize simulation accuracy, which is especially important for next-generation processes. Due to the significantly low loss characteristic of LIGENTEC’s AN core technology, the fidelity of imported material data is critical to simulation quality.

With its HEAT and CHARGE solvers, Lumerical’s DEVICE Suite provides multiphysics simulation capabilities and workflows to model the interaction between optical, electrical and thermal effects at the physical level. HEAT provides designers with comprehensive 3D finite element thermal modeling capabilities, including self-consistent simulation of heat sources driven by electrical currents. By incorporating accurate spatial variations of temperature into the optical material models for photonic simulations, designers can engineer optical components with robust and stable responses of over the full range of operating conditions.

Photonics Circuit Company LIGENTEC strengthen board with experienced photonics & sensors executive. Thomas Hessler joins LIGENTEC Board of Directors.
LIGENTEC, supplier of photonic integrated chips and chip-based components announced the appointment of Dr. Thomas Hessler as a new member to the Board of Directors.

“His leadership skills and insights are to be put to good use to support the next stage of growth for LIGENTEC. Thomas brings with him his holistic approach and hands on knowledge, built over years of experience, growing a company, along with an extensive network of professionals and makers. Access to both, knowledge and network, is setting LIGENTEC up for success.“, said Dr. Michael Zervas, co-founder of LIGENTEC.

“Thomas is a very valuable addition to our company in several aspects: He does not only bring his knowledge of the Swiss ecosystem and his worldwide connections to key market players, but also understands the technology and its potential to open new market areas that still have to be developed.’’ adds Dr. Michael Geiselmann, co-founder of LIGENTEC.

Dr. Thomas Hessler brings over 20 years of experience in executive management in the high-tech B2B environment, namely photonics and sensor. After obtaining his PhD in applied optics, he started a corporate venture, leading to Axetris AG, and developed the company to a market leader for micro-optics, optical gas sensing components and specialty MEMS foundry services with applications in the automotive, medical, analytical and industrial space.

“LIGENTEC’s groundbreaking all-nitride-core technology combines low propagation loss with small device structures,” says Dr. Hessler, “it offers the best of two worlds compared to conventional photonic integration technologies. Its possibility to be integrated easily with fibers and active functionalities will be key to achieve success in many PIC applications such as datacom, space, LiDAR and sensing. I’m excited to join this great entrepreneurial team at LIGENTEC.”

About LIGENTEC
LIGENTEC manufactures Photonic Integrated Circuits (PICs) for customers in high-tech areas such as datacom, quantum technologies, space, LiDAR and sensing. LIGENTEC commercializes the all-nitride-core technology, through which it enables customers to develop their products in the industrial revolution 4.0. Photonic integration enables to downsize optical components onto a chip, making optical operations much more power efficient at a miniaturized footprint and brings the scaling in volume and price.

VPIphotonics, LIGENTEC, and VLC Photonics streamline the design process for SiN Photonic Integrated Circuits.
Designers that use LIGENTEC AN technology will now benefit from a workflow that starts from a graphical photonic integrated circuit design and system simulation environment, which seamlessly couples to layout design tools for scripted layout design and DRC capabilities. The new workflow is based on LIGENTEC and VLC Photonics verified reference designs with the simulation software by VPIphotonics using verified measurements of fabricated chips.

This workflow is enabled by the new VPItoolkit PDK LIGENTEC – a pluggable toolkit extension to VPIcomponentMaker Photonic Circuits by adding the support of the 800 nm Silicon Nitride process “AN800” offered by LIGENTEC for dedicated shuttle runs and Multi-Project Wafer (MPW) runs.

With the mode fully confined in the waveguide the thick Silicon Nitride waveguides supported by the AN800 process with 800 nm LPCVD silicon nitride offer very tight bending radius (< 0.005 dB for 10 turns), very low coupling losses (< 1.5 dB/facet), very low propagation losses (< 0.1 dB/cm) and very high power handling (up to 10 W tested).

VPIcomponentMaker Photonic Circuits is a professional simulation and design environment for large-scale photonic integrated circuits that offers a large mix of general-purpose photonic, electrical and optoelectronic device models, together with the advanced circuit optimization and yield analysis capabilities. The library extension VPItoolkit PDK LIGENTEC adds foundry- certified simulation compact models for the standard building blocks supported by the AN800 process and enables a layout-aware schematic-driven PIC design workflow, including chip layout optimization according to its required optical functionality. Importantly, it allows designers to construct their own hierarchical and custom building blocks, effectively expanding the foundry PDK to fit individual needs. The layout for the designed photonic integrated circuits can be automatically exported to either IPKISS by Luceda Photonics or OptoDesigner by Synopsys for DRC verification and GDS mask generation.

The mature library of photonic building blocks, available at the LIGENTEC Process Design Kit (PDK), has been developed by LIGENTEC and VLC Photonics over several iterations. The capability of embedding these blocks into the VPIphotonics software framework enables the simulation and modeling of complex photonic integrated circuits with a high degree of reliability.
