Photon pair generation in hydrogenated amorphous silicon microring resonators

Elizabeth Hemsley, Damien Bonneau, Jason Pelc +3

We generate photon pairs in a-Si:H microrings using a CW pump, and find the Kerr coefficient of a-Si:H to be $3.73\pm 0.25\times 10^{-17}{m}^2/W$. By measuring the Q factor with co…
