Abstract

We demonstrate highly efficient photon-pair generation using an 8 mm long hydrogenated amorphous silicon (a-Si:H) waveguide in far-detuned multiple wavelength channels simultaneously, measuring a coincidence-to-accidental ratio as high as 400. We also characterize the contamination from Raman scattering and show it to be insignificant over a spectrum span of at least 5 THz. Our results highlight a-Si:H as a potential high-performance, CMOS-compatible platform for large-scale quantum applications, particularly those based on the use of multiplexed quantum signals.
