Abstract

Vertical cavity surface emitting laser (VCSEL) based short reach optical solutions are widely deployed in the applications with the aggregated data rate from 10 Gb/s to 400 Gb/s and transmission distance less than 100m. Even with the great advantages of power consumption and cost, 100 Gb/s per lane multimode interconnect is still at stake due to the great challenges imposed by VCSEL design and multimode transmission. Besides the bandwidth challenge, co-design of VCSEL and electrical driver in both circuit and packaging level become significantly important with electrical and photonic chips getting close in a co-package form factor. In this paper, we will establish the theory on the VCSEL modeling and propose a comprehensive electro-optical co-design framework for power-efficient high-speed VCSEL transmitter targeting at 50 Gbaud. Bandwidth enhancement based on photon-photon resonance is also investigated with VCSELs injection locked by an optical frequency comb.
