Using two-photon (Franson) interferometry, we measure the entanglement of photon pairs generated from an optically-pumped silicon photonic device consisting of a few coupled microring resonators. The pair-source chip operates at room temperature, and the InGaAs single-photon avalanche detectors (SPADs) are thermo-electrically cooled to 234K. Such a device can be integrated with other components for practical entangled photon-pair generation at telecommunications wavelengths.
