Title:  VCSEL-based Multimode Fiber Optical Links for High Capacity Interconnects


Dr. Ralph, Advisor

Dr. Klein, Chair

Dr. Chang


The objective of the proposed research is to develop and demonstrate new system archetypes for increasing optical interconnect (server-to-server) data rate capacity in data center and high performance computing applications. This proposal will overview the main impairments of a vertical-cavity surface-emitting laser (VCSEL) based link, noise analysis of VCSELs and the impact of fiber on noise, advanced modulation formats (PAM-4), optical power penalties associated with faster line rates, transmitter equalization, and few tap transmitter pulse shaping.
