Abstract

We demonstrate the monolithic integration of a photonic crystal (PhC) laser and a photodetector with which to construct on-chip interconnect. By combining an ultracompact embedded active region and a PhC cavity, the laser exhibits an ultra-low threshold current of 22 μA and an integrated optical link operates at an ultra-low energy of 28.5 fJ/bit.
