Abstract

Coupled optoelectronic oscillator (COEO) is a combination of an optoelectronic oscillator loop and a mode-locked fiber laser loop sharing the same electro-optical modulator. It has the capability of generating both radio frequency (RF) signals and optical pulses with high quality. In this paper, a theoretical model for COEO with a high supermode suppression ratio (SMSR) is established. Numerical simulations are carried out. The impacts of the used electrical bandpass filter on the SMSR of the generated optical pulses and the phase noise of the generated RF signals in the COEO are analyzed and investigated. Through mathematical simulations, the variation trends of the SMSR values of the optical pulses, and the phase noise values of the generated RF signals versus the characteristics of the used electrical bandpass filter are given. Stable optical pulse trains and RF signals are both successfully generated with high quality for the 10- and 40- GHz COEOs. The SMSR values higher than 80 dB are achieved.
