Abstract
An optical receiver includes an optical amplifier that is optically connected to a local oscillator (LO) and a plurality of optical hybrid mixers of the optical receiver and that is electrically connected to a controller. The optical amplifier is configured to receive an optical LO signal from the LO, receive a voltage value associated with an optical input signal of the optical receiver, control a power of the optical LO signal based on the voltage value, and provide, after adjusting the power of the optical LO signal, the optical LO signal to the plurality of optical hybrid mixers. The controller, is configured to determine the voltage value associated with the optical input signal and cause the voltage value to be provided to the optical amplifier.
