1. A device, comprising:

  • an oscillator producing an electrical oscillation signal; and

    an opto-electronic oscillator comprising a positive feedback loop which comprises an optical section, an electrical section, and an optical detector to connect the optical section and the electrical section, wherein the optical section comprises an optical modulator modulating light under control of an electrical output signal from the electrical section and an optical delay line to receive an optical output of the optical modulator, wherein the electrical section is coupled to receive the electrical oscillation signal from the oscillator and to send an electrical signal in the electrical section into the oscillator to suppress phase noise in the oscillator.
