Monolithically integrated III-V/Si comb lasers for silicon photonic optical I/O

Optical frequency comb (OFC) sources have attracted significant attentions over the past few years. Silicon based semiconductor mode-locked lasers (MLLs) can provide coherent optical frequency combs with high repetition rates and output power, which have been recognized as potential multi-wavelength sources for optical I/O due to their compactness, high-efficiency, and low-cost properties. Here, we demonstrated monolithically grown III-V quantum dot lasers on SOI substrates for integrated optical I/O with transmission capcity over 1.6 Tbps.
