20-Gb/s power-efficient CMOS-driven multimode links

Abstract

We report several firsts for CMOS-driven, VCSEL-based, multimode transmitters and receivers: serial links up to 20 Gb/s; unprecedented full-link power efficiencies from 8 pJ/bit (15 Gb/s) to 17 pJ/bit (20 Gb/s); and >25-Gb/s transmitter operation. © OSA/OFC/NFOEC 2011.
