INTEGRATED PRODUCTION OF SELF INJECTION LOCKED SELF PHASE LOOP LOCKED OPTOELECTRONIC OSCILLATOR

摘要

The present invention details fabrication guidelines of integrated optoelectronic oscillators with frequency and phase stability, having higher frequency selectivity in a relatively small size (compared to the larger size of a higher order electrically realized RF filter), reduced temperature sensitivity, and minimized frequency drift. The integrated photonic components and RF oscillator may use Silicon photonics and microelectronic integration using CMOS and BiCMOS technology, eliminating the need for bulky and/or discrete optical and microwave components.

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.
