v2024 Release Announcement

crosslight — Mon, 16 Dec 2024 17:08:36 +0000

Crosslight is proud to announce new features & milestones for its upcoming v2024 release. In addition to multiple bug fixes and improvements, the following new feature/improvements were made:

Improved behavior of negative stimulated emission rate for EAM and waveguide photodetectors
Complete overhaul of commands in the bias_output family, to provide more extensive diagnostic plots of internal variables during a simulation
Improved regrid functionality, with optional Delaunay mesh generator
Improved regrid functionality, providing the ability to reload the refined mesh and continue the simulation
New model for PCSEL devices
Improvements to mode selection methods in microcavity model
Enhanced plotting of AC LED characteristics
New model for quantum cascade photodetectors
Modified behavior of RCLED model, to better diagnose issues with accidentally mistuned cavities
Improved randomness settings for resistive switch model
Added additional flexibility to define multiple dopant types in layer files

This version will be released shortly to eligible customers. Customers with an up-to-date maintenance contract may also contact their local sales representatives if they wish to try these new features right away.

v2023 Release Announcement

crosslight — Wed, 20 Dec 2023 21:10:08 +0000

Crosslight is proud to announce new features & milestones for its upcoming v2023 release. In addition to multiple bug fixes and improvements, the following new feature/improvements were made:

New emission spectrum model for microcavity structures, based on Green’s function theory
The full 3D microcavity model has been upgraded to support symmetric boundary conditions. This enhancement enables PICS3D to save on mesh and simulation time buy solving either half or a quarter of the device. This flexibility is particularly beneficial for large or complex devices such as Photonic Crystal VCSELs and High Contrast Grating VCSELs
New faster and memory-efficient eigensolvers available. These are automatically implemented for the optical mode solution in the microcavity model
New compressed (zip) format available for the import/export of gain tables. This speeds up the process of loading material gain data from external solvers and allows for denser tables to be used more easily.

This version will be released in the coming weeks, 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.

Next Generation 3D Simulator for Surface Emitting Lasers

crosslight — Tue, 05 Dec 2023 18:37:16 +0000

We are pleased to announce that our proposal “Next Generation 3D Simulator for Surface Emitting Lasers” has been approved for support under the National Research Council Canada’s Industrial Research Assistance Program (NRC-IRAP).

Over the coming year, expect more PCSEL-related news as we continue to improve the software to handle this exciting new class of laser devices.

New Oxide VCSEL presentation
