We report the design of an integrated photon pair source based on spontaneous four wave mixing (SFWM), implemented in an integrated micro-ring resonator in the silicon nitride platform (Si₃N₄). The signal photon is generated with emission at 606 nm and bandwidth of 3.98 MHz, matching the spectral properties of Praseodymium ions (Pr), while the idler photon is generated at 1430.5 nm matching the wavelength of a CWDM channel in the E-band. This novel device is designed to interact with a quantum memory based on a Y₂SiO₅ crystal doped with Pr³+ ions, in which, we used cavity-enhanced SFWM along with dispersion engineering to reach the required wavelength and the few megahertz signal photon spectral bandwidth.
