Time-correlated Photons from a In\(_{0.5}\)Ga\(_{0.5}\)P Photonic Crystal Cavity on a Silicon Chip

Time-correlated photon pairs are generated by triply-resonant Four-Wave-Mixing in a In\(_{0.5}\)Ga\(_{0.5}\)P Photonic Crystal cavitiy. Maximal efficiency is reached by actively compensating the residual spectral misalignment of the cavity modes. The generation rate reaches 5 MHz in cavities with Q-...

Description
Summary:Time-correlated photon pairs are generated by triply-resonant Four-Wave-Mixing in a In\(_{0.5}\)Ga\(_{0.5}\)P Photonic Crystal cavitiy. Maximal efficiency is reached by actively compensating the residual spectral misalignment of the cavity modes. The generation rate reaches 5 MHz in cavities with Q-factor \(\approx 4\times 10^4\), 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.
