Photon pair generation in hydrogenated amorphous silicon microring resonators

Autor: Hemsley, Elizabeth, Bonneau, Damien, Pelc, Jason, Beausoleil, Ray, O'Brien, Jeremy L., Thompson, Mark G.

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 coupled power we find that the loss in the a-Si:H micro-rings scales lin

Active Temporal Multiplexing of Photons

Autor: Mendoza, Gabriel J., Santagati, Raffaele, Munns, Jack, Hemsley, Elizabeth, Piekarek, Mateusz, Martin-Lopez, Enrique, Marshall, Graham D., Bonneau, Damien, Thompson, Mark G., O'Brien, Jeremy L.

Photonic qubits constitute a leading platform to disruptive quantum technologies due to their unique low-noise properties. The cost of the photonic approach is the non-deterministic nature of many of the processes, including single-photon generation,

We demonstrate experimentally critical coupling for nonlinear conversion in grating-coupled Fabry-Pérot planar microcavities known as Cavity-Resonant Integrated Grating Filters (CRIGFs). Novel asymmetric designs offer Q-factors from 1000 to 7000 and
