Abstract
The high Kerr coefficient of amorphous silicon makes it a promising material for generating photons on chip via spontaneous four wave mixing (SFWM), for applications in quantum photonics. Previous work shows high photon generation rates in a-Si waveguides, [1], and here we expand this study to investigate micro-ring resonator photon sources, which have a small footprint and can produce photons with high spectral purity, ideal for quantum interference. We compare SFWM generation rates in an a-Si micro-ring resonator to a straight waveguide, in both continuous wave and pulsed pump regimes.
