We experimentally demonstrate photon pair generation through spontaneous four-wave mixing in a silicon micro-ring resonator. We report a coincidence-to-accidental (CAR) ratio of 456\pm18 using the full width half maximum of the coincidence histogram as the integration window. In order to overcome the free-carrier related performance degradation we have investigated reverse biasing the ring. We show that this method improves the pair generation rate by a factor of up to 2.1.
