ABSTRACT:
A photonic oscillator includes an optical transceiver that serves the dual purpose of detecting a feedback RF lightwave signal carried on a laser beam and electrically filtering the RF lightwave signal to modulate the RF lightwave signal in accordance therewith, to thereby set up steady state oscillations in the modulated RF lightwave signal and thereby generate a multi-tone oscillating lightwave.
