TitleVCSEL-based Multimode Fiber Optical Links for High Capacity Interconnects


Dr. Stephen Ralph, ECE, Chair , Advisor

Dr. Benjamin Klein, ECE

Dr. Gee-Kung Chang, ECE

Dr. Doug Yoder, ECE

Dr. Rick Trebino, Physics


Advancements in fiber optic communication will require development and demonstration of new systems for increasing optical interconnect (server-to-server) data rate capacity in data center and high performance computing applications. This research will cover the main impairments of a vertical-cavity surface-emitting laser (VCSEL) based links, noise analysis of VCSELs and the impact of fiber on noise, advanced modulation formats (PAM-4), shortwave division multiplexing (SWDM), optical power penalties associated with faster line rates, transmitter equalization, and few tap transmitter pulse shaping, for realizing these new systems.
