Abstract

We demonstrate on-chip generation of correlated pairs of photons in the near-visible spectrum using a CMOS compatible plasma-enhanced chemical vapor deposition silicon nitride photonic device. Photons are generated via spontaneous four wave mixing enhanced by a ring resonator with high intrinsic quality $Q$-factor of 320,000, resulting in a generation rate of $\mathrm{950,000}\frac{\text{pairs}}{\mathrm{mW}}$. The high brightness of this source offers the opportunity to expand photonic quantum technologies over a broad wavelength range and provides a path to develop fully integrated quantum chips working at room temperature.
