An optoelectronic oscillator based on dual-lasers

Abstract

A novel optoelectronic oscillator (OEO) based on dual-lasers is demonstrated in this paper. The oscillator takes advantage of the dual optical fiber loops with different mode separations, which induces the gain competition and leads to high side-mode suppressed ratio (SMSR). Besides, the OEO can also suppress the random interference and the beating noise when single laser source is used. Finally, the results are as follows: the operating frequency is 4.998 GHz, the phase noise is 113 dBc/Hz at 10 kHz, the SMSR is more than 60 dB, and the time jitter is 289 fs.
