Complementary metal-oxide semiconductor compatible source of single photons at near-visible wavelengths

Complementary metal-oxide semiconductor compatible source of single photons at near-visible wavelengths
Complementary metal-oxide semiconductor compatible source of single photons at near-visible wavelengths
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 3,20,000, resulting in a generation rate of 950,000  pairs-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.

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 3,20,000, resulting in a generation rate of 950,000  pairs-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.
