Chen served as the CTO, Founder, and Chairman of the Board of Radiant Research, Inc. from 2000 to 2001, where he raised 18 million dollars A-Round funding to commercialize polymer-based photonic devices involving over twenty patents, which were acquired by Finisar in 2002, a publicly traded company in the Silicon Valley (NASDAQ:FNSR). He also serves as the founder and Chairman of the Board of Omega Optics Inc. since its initiation in 2001. Omega Optics has received over twenty million dollars in research funding from private sectors and government agencies. His research work has been awarded over 150 research grants and contracts from such sponsors as Army, Navy, Air Force, DARPA, MDA, NSA, NSF, DOE, EPA, NIST, NIH, NASA, the State of Texas, and private industry. The research topics are focused on four main subjects: (1) Nano-photonic passive and active devices for bio- and EM-wave sensing and interconnect applications, (2) Thin film guided-wave optical interconnection, computing and packaging for 2D and 3D laser beam routing and steering, (3) True time delay (TTD) wide band phased array antenna (PAA), and (4). 3D printed micro-electronics and photonics. Experiences garnered through these programs are pivotal elements for his research and further commercialization.
