Abstract
An optical receiver includes a photonic integrator configured to accumulate optical signal energy corresponding to the input optical signal during an integration period, and to produce an output optical signal at an end of the integration period, the output optical signal having a higher intensity than the input optical signal, a shutter operable between a closed position and an open position, the shutter configured to prevent the output optical signal from exiting the photonic integrator when in the closed position and to allow the output optical signal to exit the photonic integrator when in the open position, a synchronizer coupled to the shutter and configured to control the shutter between the open position and the closed position; and a photodetector configured to receive the output optical signal when the shutter is in the open position and to produce an electrical signal corresponding to the output optical signal.
