摘要：We propose and demonstrate a tunable optoelectronic oscillator (TOEO) based on coupled double loops (CDLs) and stimulated Brillouin scattering (SBS). By the incorporation of CDLs and SBS, we not only improve the side-mode suppression ration (SMSR) of the SBS-based OEO, but also enhance the stability of the generated signals. Microwave signals with a tunable range from 2 GHz to 18 GHz are generated. The phase noise is lower than -90 dBc/Hz at 10 kHz frequency offset and the SMSR is superior to 60 dB when the oscillation frequency tuned from 2 GHz to 18 GHz. Furthermore, the power excursion is below 0.2 dB and the frequency excursion is less than 0.3 ppm at 10 GHz in lab condition within 30 minutes, which proved the stability of the generated signals.
