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... Hits: 3934 Download times: 223 View Full Text    Download reader
