Optoelectronic oscillator based on fiber ring resonator: Overall system optimization and phase noise reduction

Abstract

Theoretical and experimental optimization studies are presented in this paper, where the aim is to improve the phase noise of an optoelectronic oscillator based on a passive fiber ring resonator. Our experimental results demonstrate a significant reduction in the phase noise of the final optimized system, which is also compared to the best existing oscillator of the same type, an active cavity based coupled optoelectronic oscillator.
