A new model for SiGe modulators has been added to our standard PICS3D example library starting with version 2023. Interested demo users and existing maintenance customers can contact us to get early access to the 2023 beta version and the files needed to run this example.

A new model for High Contrast Grating Crystal Vertical Surface Emitting Laser (HCG-VCSEL) model has been demonstrated for our beta version of PICS3D, making use of our latest improvements in the vectorial FDFD solver of the Maxwell equations. Interested demo users and existing maintenance customers can contact us to get early access to the 2023 beta version and the files needed to run this example.

We are proud to announce the fourth annual winner of a collaboration with Assistant Professor Can Bayram of the University of Illinois at Urbana-Champaign. As part of this collaboration, students worked with Crosslight TCAD tools in an academic setting and the best projects were selected for a prize.

Congratulations to the 2023 winner of this award:

• NITHIYASSRI K R T VIVAGANDAN Designing Blue-Wavelength Free White Light: A Dichromatic Approach Using Violet and Yellow-Green LEDs

Crosslight is proud to announce new features & milestones for its upcoming v2022 release. In addition to multiple bug fixes and improvements, the following new feature/improvements were made:

• VCSEL model for multiple tunneling junctions has been improved so that more accurate optical output can be extracted from the simulation.
• Significant improvements in speed, accuracy, and ease of use for the microcavity FDFD model. This model is now recommended for complex VCSEL structures, including devices with multiple tunnel junctions.
• Hot carrier injection/trap generation model for thin film transistors.
• Updated AC models.
• New 3D mesh generation system.

This version will be released later this year, after final testing has been completed. Customers with an up-to-date maintenance contract can contact their local sales representatives if they wish to try these new features right away.

Congratulations to the 2022 winners of this award:

• Jaekwon Lee for 2D Optical-Thermal-Electrical Simulation for High Wall Plug Efficiency Cubic GaN Green LED on Silicon
• Robert Kaufman for HgCdTe Long-Wave Infrared Photovoltaics for Directed Energy Applications

A new presentation on our microcavity model has been added to our Laser Diodes application page.

A copy of a talk given at the CASICON2021 conference by our CEO and founder, Dr. Simon Li, has been uploaded to our Miscellaneous Conferences page.

A new presentation on how to convert existing VCSEL input files from a scalar model to a full vectorial solution has been posted to our Laser Diodes application page.

Crosslight is proud to announce new features & milestones for its upcoming v2021 release. In addition to multiple bug fixes and improvements, the following
new feature/improvements were made:

• LINUX platform release Process and Device simulation with improved GUI support
• Metal/semiconductor interface to support the same metal in contact with multiple regions of semiconductor
• Hot carrier injection model implemented using hydrodynamic TCAD simulation to support modeling of long term reliability related to hot carrier injection in transistors
• Hydrogen and other impurity diffusion common in TFT process
• Interface between LTSpice project files and mixed-mode TCAD simulation, so that it is convenient to start with a LTSpice simulation when adding circuit elements to TCAD simulation.
• Field-induced trap emission (Poole-Frenkel) model
• VCSEL/TMM model improved to handle tunnel juction cascade MQW VCSEL
• Special treatment minority carrier in wide bandgap materials enhanced to improve convergence
• Mesh-bending model improved to treat TFT-OLED with multiple cells

This version will be released later this year, after final testing has been completed. Customers with an up-to-date maintenance contract can contact their local sales representatives if they wish to try these new features right away.
