CHAMPAIGN-URBANA, ILLINOIS – September 28, 2004 – Today, Illinois based EpiWorks, Inc., a leading developer and manufacturer of compound semiconductor epitaxial wafers, and Professor Kent Choquette, a faculty member at the University of Illinois at Urbana-Champaign announced a new VCSEL result developed through a formal collaborative research agreement.
“VCSELs are key optical devices in gigabit ethernet networking systems as well as many emerging applications, such as printing, medical, bar code scanning and display applications. The primary goal of this work is to implement novel designs and explore new capabilities and applications. We have successfully completed the first phase of the program which is the implementation of a ‘n-up’ 850 nm VCSEL,” said Professor Kent Choquette, the principle investigator responsible for the project within the Micro and Nanotechnology Laboratory at the University of Illinois. “In the next stage we plan to use this capability to demonstrate more complex device designs.”
The 850 nm VCSEL performance parameters include Ith= 800 µA, Power = 6 mW @ 10 mA, for an oxide confined 5 µm diameter device.
“We are extremely pleased to have successfully reached the first milestone of developing a VCSEL capability through this collaboration,” said Dr. Xiuling Li, EpiWorks’ Manager of R&D. “VCSELs are challenging devices to manufacture, but we are looking forward pushing the technology to the next level.”
