Dr. Chris Chase
Christopher Chase received his B. E. E. degree from the University of Minnesota-Twin Cities in 2005 in Electrical Engineering and a Ph.D. from U.C. Berkeley in 2011 in Electrical Engineering. He investigated high contrast grating integration in tunable and long wavelength VCSELs in his dissertation research. He has spent the last 5 years at Bandwidth10 in Berkeley, CA developing tunable VCSEL products for optical network and sensor applications.
Low cost tunable lasers are a key component for the implementation of next generation optical access networks. The lack of a commercially available, low-cost tunable transceiver has hindered the implementation of higher speed, WDM (wavelength division multiplexed) capable access networks. In this talk, we will present Bandwidth10’s work implementing tunable VCSELs with high contrast gratings, achieving ~25 nm mechanical tuning range and over 3 mW output power. Error-free operation of an optical link using directly-modulated tunable VCSEL-based transceivers transmitting at 10 Gbps over 16 channels and transmitted over 10 km of single mode fiber is demonstrated, showing the suitability of the HCG tunable VCSEL as a low cost source for next generation WDM communications systems in access networks.
