A Low Phase Noise 10 GHz Optoelectronic RF Oscillator Implemented Using CMOS Photonics

The emerging wireless communications standards at higher frequencies, especially toward 60 and 80 GHz, are challenged by the availability of cost-effective high performance oscillators. Since the bandwidth of a wireless communications system is heavily dependent on the phase noise of the local oscillator, spectral efficiency at these frequencies is limited to a fraction of that achieved in cellular, WiFi, and WiMax applications using available local oscillators (LO).
