First Commercially Scalable Integrated Laser and Microcomb on a Single Chip


Housing and Development Newsletter
Importantly, the new technology lends itself to commercial-scale production, because thousands of devices can be made from a single wafer using industry standard complementary metal oxide semiconductor (CMOS)-compatible techniques.
“Our approach paves the way for large-volume, low-cost manufacturing of chip-based frequency combs for next-generation high-capacity transceivers, datacenters, space and mobile platforms,” the researchers stated.
The key challenge in making the device was that the semiconductor laser and the resonator, which generates the comb, had to be built on different material platforms. The lasers can be made only with materials from the III and V groups on the Periodic Table, such as indium phosphide, and the best combs can be made only from silicon nitride. ....

Steven DenBaars, John Bowers Recognized at Compound Semiconductor Week Conference


Housing and Development Newsletter
According to ISCS, DenBaars “has made seminal contributions to the science of nitride materials, and is recognized as an international authority on the growth and structure of nitride semiconductors by metal-organic chemical vapor deposition (MOCVD). He has performed pioneering work on polar, non-polar and semi-polar Gallium nitride (GaN) materials and devices.”
A professor of materials who holds the university’s Mitsubishi Chemical Chair, DenBaars joined the campus in 1991. In 1997 he and fellow GaN expert Umesh Mishra co-founded Nitres, Inc., one of the first GaN startups in the United States. Nitres was acquired by Cree, Inc. in May 2000. ....
