Optically Biased Photonic Transmitter and Detector

Abstract

An optically biased photonic link receives a radiofrequency (RF) signal and includes a signal laser joined to an optical intensity modulator. A low noise amplifier receives the RF signal and provides an amplified signal to the modulator.The modulator converts the signal into an optical signal. The optical signal is received by a link receiver which provides an analysis signal and an output signal. A bias logic circuit uses the analysis signal to provide an optical bias signal to an optical detector joined to modulator. The optical detector provides a responsive bias voltage to the modulator. The optical detector can provide a positive bias control signal or a negative bias control signal.
