Abstract
An optically biased photonic link receives a radio frequency (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 amplifier and modulator are powered by a photovoltaic array. The array receives power from a remotely located power laser. 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.
