摘要：

Time-correlated photon pairs are generated by triply resonant four-wave-mixing in an In0.5Ga0.5P photonic crystal cavity. Maximal efficiency is reached by actively compensating for the residual spectral misalignment of the cavity modes. The generation rate reaches 5 MHz in cavities with a Q-factor approximate to 4 x 104 , more than one order of magnitude larger than what is measured using ring resonators with similar Q factors fabricated on the same chip. The photonic crystal source is integrated on a Si photonic circuit, an important asset for applications in quantum technologies.
