Error-Free Operation in a Hybrid-Silicon Quantum Dot Comb Laser 
Date: Nov 17, 2017
We investigate amplitude noise in a wafer-bonded quantum dot laser on silicon. Error-free operation at room temperature and under continuous current injection in the three highest-power channels is observed with a signal-to-noise ratio of 11.5 dB or larger. These devices are attractive candidates as an optical engine for interconnects in next-generation data centers and exascale computers.
