Abstract
An example photon detecting system includes a detector component optically coupled to a waveguide and configured to detect one or more photons from the waveguide. The example photon detecting system further includes an optical switch configured to selectively couple the waveguide to an optical source, wherein the optical switch is configured to de-couple the waveguide from the optical input in accordance with the detector component being in an inactive state. The example photon detecting system also includes readout circuitry coupled to the detector component.
