1. A monolithically integrated optoelectronic oscillation circuit for sustaining an oscillating optical signal, comprising:

  • an injection locking circuit comprising at least one fiber optic delay line configured to receive a first portion of the optical signal;

    a phase lock loop circuit comprising at least two fiber optic delay lines configured to receive other portions of the optical signal;

    a monolithically integrated voltage controlled oscillator configured to generate a stable oscillating signal in response to each of an injection locking signal derived from the first portion of the optical signal and a phase lock loop signal derived from the other portions of the optical signal, the stable oscillating signal being configured to RF modulate the optical signal.
