Abstract

We present chip-scale lasers with ~1Hz fundamental linewidths, ~30Hz integral linewidths, and stability better than 2x10-13 (50ms) enabling energy-efficient, ultra-low residual phase error carrier recovery for DSP-free, high-capacity coherent communications in tomorrow's data center interconnects.
