1. A photonic oscillator, comprising:
- an optical combiner configured to combine a laser beam with a second RF lightwave signal to generate a first RF lightwave signal;
an optical transceiver configured to detect the first RF lightwave signal, electrically filter the detected first RF lightwave signal, and modulate the detected first RF lightwave signal in accordance with the filtered first RF lightwave signal;
an optical delay path configured to delay the modulated first RF lightwave signal; and
an optical splitter configured to split the delayed modulated first RF lightwave signal into the second RF lightwave signal and a third RF lightwave signal.

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.
