提出并通过实验证明了一种基于受激布里渊散射（SBS）和相位调制的电可调倍频光电振荡器（OEO）。在这种OEO配置中，相位调制器与光学滤波器相结合用于产生倍频微波信号，而SBS效应提供窄带滤波并确保反馈驱动信号在基频上振荡。通过改变双边带载波抑制调制获得的布里渊泵浦信号，实现频率可调。在我们的实验中，当施加到强度调制器的调谐信号从 200 MHz 调谐到 2 GHz 时，会生成从 21.4 GHz 到 25 GHz 的连续可调谐倍频信号。
An electrically tunable frequency-doubling optoelectronic oscillator (OEO) with operation based on stimulated Brillouin scattering (SBS) and phase modulation is proposed and experimentally demonstrated. In this OEO configuration, the phase modulator in combination with an optical filter is employed to produce a frequency-doubling microwave signal, while the SBS effect provides the narrowband filtering and ensures the oscillation of the feedback driving signal at the fundamental frequency. By varying the Brillouin pump signal obtained from double-sideband–carrier-suppression modulation, the frequency tunability is realized. In our experiment, a continuous tunable frequency-doubling signal from 21.4 to 25 GHz is generated when the tuning signal applied to the intensity modulator is tuned from 200 MHz to 2 GHz.
