Crosslight is pround to announce a technical breakthrough in the device modeling of semiconductor optoelectronic devices: 2/3D simulation of microcavity laser diodes. The new modeling abandons the traditional approach of separating solutions of longitudinal and lateral modes and solves the Maxwell wave equations in all directions rigorously for all eigen modes operating at different wavelengths.

The microcavity option of PICS3D finds applications in VCSEL, RCLED, QD-LD/QD-LED, and microdisk lasers, where optical modes couple in different directions. A demonstration of the model as applied to surface relief VCSELs may be found in this presentation.

Crosslight Software is pleased to announce that we are entering into a partnership with Dr. Gary Dolny, who will act as an adviser on the development and applications of Crosslight’s state-of-the-art TCAD simulation tools with emphasis on power and analog devices.

Dr. Dolny holds a Ph.D. in Electrical Engineering from the University of Pittsburgh and has more than 35 years’ experience in the industry with companies including RCA Laboratories, Sarnoff Corporation (now SRI International), Harris Semiconductor, Intersil Corp and Fairchild Semiconductor, where he achieved the rank of Technical Fellow. He has published approximately 80 papers in peer-reviewed conferences and technical journals, received two conference best paper awards and has been awarded approximately 40 U.S. patents. He is a Senior Member of the IEEE, has served on the organizing committee of the International Devices Meeting (IEDM) and the International Symposium on Power Semiconductor Devices and ICs (ISPSD) and has served as Editor of both IEEE Transactions on Electron Devices and IEEE Electron Device Letters in the area of Solid State Power and High Voltage Devices.

For more details, please contact Crosslight or Dr. Dolny.

As part of its 20-year anniversary coverage, Compound Semiconductor magazine has a featured article on Crosslight, which also celebrates its 20th anniversary this year.

Crosslight is proud to announce that the ability to generate .mdm files compatible with the popular IC-CAP parameter extraction program has been added to the 2015 version. This feature allows users to easily bridge the gap between device-scale modeling with Crosslight TCAD tools and large-scale IC modeling based on SPICE.

We at Crosslight always seek to innovate and expand our product line so we are proud to announce the release of the world’s first commercial 3D TCAD simulator specialized in surface acoustic wave (SAW) device simulation. Our new simulation package SAWAVE aims to provide an accurate and efficient design tool for the SAW industry.

For a 2-month no-obligation free demo of SAWAVE, please fill out the application form in our Downloads section.

Crosslight is proud to announce that our 2015 version is now undergoing final testing.

Crosslight would like to invite all participants of the upcoming Photonics West conference in San Francisco to attend a free seminar and software tutorial on optoelectronic device simulation. The tutorial gives a hands-on introduction to our high-end simulation tools for electronic and optoelectronic devices: APSYS, LASTIP and PICS3D. These software packages combine electrical, thermal, optical, and quantum-mechanical models in two or three dimensions and can be applied to a large variety of semiconductor devices such as laser diodes, LEDs, solar cells and transistors.

The tutorial will explain and demonstrate the basic operation of these software tools. Strategies for setting the right model options and material parameters to obtain realistic simulation results will also be discussed. Using realistic device examples, deep insight into micro- and nano-scale physical processes will be provided .

The seminar will be held on Thu. Feb. 12th 1PM – 5PM in the Sierra A room of the Marriott Marquis hotel. More information on the tutorial can be obtained at the conference’s Industry Events page.

While the seminar is free, preregistration from interested participants would be appreciated. Attendees who wish to participate in the hands-on part of the tutorial are also advised to bring along their Windows-based laptop and visit the Crosslight booth (#4517) in the North Exhibit Hall prior to the seminar for help in setting up the software.

We are pleased to announce that a new tutorial movie for GaN HEMT has been uploaded. GaN HEMT is widely believed to be the next generation of power devices and this technology is expected to drive a market worth billions of dollars in annual revenue in the near future. As a world leader in compound semiconductor device modeling, Crosslight intends to build on its two decades of experience and will focus its efforts on the development of best-in-class device and process simulation tools for GaN power HEMT devices.
