Photon pair generation using spontaneous four-wave mixing (SFWM) in microring resonators on a photonic silicon chip — •Florian Vogel, Erik Fitzke, Jakob Kaltwasser, and Thomas Walther — TU Darmstadt, Institute of Applied Physics, 64289 Darmstadt

We employ spontaneous four-wave mixing (SFWM) in ring resonators on a photonic chip with silicon nitride waveguides to generate a photon pair spectrum with a spectral shape determined by the mode of the resonator. The frequencies of the resulting photon pairs differ by a multiple of the free spectral range and can be separated from one another by wavelength division multiplexing. Various filters are also used to remove unwanted frequency components that make it difficult to identify the photon pairs from the spectrum. A Pound-Drever-Hall (PDH)-Locking is set up for the compensation of thermal changes in the length of the resonator.
