Title: Time-correlated Photons from a In$_{0.5}$Ga$_{0.5}$P Photonic Crystal Cavity on a Silicon Chip
Authors: Alexandre Chopin, In\`es Ghorbel, Sylvain Combri\'e, Gabriel Marty, Fabrice Raineri, Alfredo De Rossi
Abstract 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. The generation rate reaches 5 MHz in cavities with Q-factor $approx 4times 104$, more than one order of magnitude larger than what is measured using ring resonators with similar Q factors fabricated on the same chip.

Abstract: 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.
