# Photon-photon interactions in dynamically coupled cavities

@article{Heuck2019PhotonphotonII, title={Photon-photon interactions in dynamically coupled cavities}, author={Mikkel Heuck and Kurt Jacobs and Dirk R. Englund}, journal={Physical Review A}, year={2019} }

We study theoretically the interaction between two photons in a nonlinear cavity. The photons are loaded into the cavity via a method we propose here, in which the input/output coupling of the cavity is effectively controlled via a tunable coupling to a second cavity mode that is itself strongly output-coupled. Incoming photon wave packets can be loaded into the cavity with high fidelity when the timescale of the control is smaller than the duration of the wave packets. Dynamically coupled…
