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.

Integrated quantum optics using silicon wire waveguides is presented. The Kerr nonlinearity of silicon allows the generation of photon pairs within straight waveguides, within micro-ring resonators, as well as the realisation of more complex circuits.

We demonstrate efficient generation of correlated photon pairs by spontaneous four wave mixing in a 5 μm radius silicon ring resonator in the telecom band around 1550 nm. By optically pumping our device with a 200 μW continuous wave laser, we obtain a pair generation rate of 0.2 MHz and demonstrate photon time correlations with a coincidence-to-accidental ratio as high as 250. The results are in good agreement with theoretical predictions and show the potential of silicon micro-ring resonators as room temperature sources for integrated quantum optics applications.
