Photonic-wire bonded pump reject and tunable wavelength demultiplexer using contra-directional couplers for a silicon micro-ring resonator photon-pair source

Abstract

A wavelength demultiplexer and pump-reject circuit using three contra-directional couplers is integrated with a silicon micro-ring resonator and connected using photonic wire bonds that achieve a pair-generation rate of 13 kHz and CAR of 320.
