提出并实现了一种基于色散感应微波光子滤波器(MPF)的压控频率可调光电振荡器，该振荡器由双平行马赫-曾德尔调制器(DPMZM)中的载波相移双边带调制、线性啁啾光纤Bragg光栅和偏振复用复合腔实现。通过简单地调节DPMZM的直流偏置电压，可以移动色散感应MPF的中心频率，并可以调谐光电振荡器的振荡频率。给出了详细的理论分析，并通过概念验证实验进行了验证。
We propose and demonstrate a voltage-controlled frequency-tunable optoelectronic oscillator based on a dispersion-induced microwave photonic filter (MPF), which is implemented with a carrier phase-shifted double sideband modulation in a dual-parallel Mach-Zehnder modulator (DPMZM), a linear chirped fiber Bragg grating and a polarization multiplexed composite cavity. By simply adjusting the DC bias voltage of the DPMZM, the central frequency of the dispersion-induced MPF is shifted and the oscillation frequency of optoelectronic oscillator can be tuned. A detail theoretical analysis is provided, which is validated by a proof of concept experiment.
