Coherent-Perfect-Absorption-based DPSK Demodulator for Silicon Photonics

We demonstrate a fully integrated 10 Gbps novel Si DPSK demodulator using coherent perfect absorption. Our device incorporates a silicon ring resonator, two bus waveguide inputs, monolithically integrated detectors, and operates passively at telecommunication wavelengths, and fits within a mm-scale footprint.
