We report a comb-like photon pair source with a high Coincidence to Accidental Ratio (CAR) in a silicon nitride microring resonator. We are able to generate up to 10 sideband pairs with a free spectral range of 378 GHz. We characterized the time and frequency correlations between th1ese sidebands via joint spectral intensity measurement. Additionally, we mapped the frequency correlations into time by applying dispersion to the photon pairs with a chirped fiber Bragg grating.
