A tunable frequency-doubling optoelectronic oscillator (OEO) is proposed and experimentally demonstrated, of which the novelty lies in the conjunction of the double-sideband suppressed carrier (DSB-SC) modulation and the carrier recovery based on stimulated Brillouin scattering (SBS) effect. Frequency-doubled signals are generated via the DSB-SC modulation, which is realized by using a polarization modulator (PolM) in combination with an optical polarizer. Then, the gain provided by the SBS effect is used to recover the suppressed optical carrier, such that a fundamental-frequency oscillating required in the OEO loop is maintained. In the experiment, frequency-doubled microwave signals at 6.1 and 20 GHz are generated and analyzed. Meanwhile, the stability of the generated signals is also investigated.
