基于受激布里渊散射的多阻带微波光子滤波器
|
摘要
基于受激布里渊散射效应,设计并实现了一种非周期性多阻带微波光子滤波器。采用可编程射频信号驱动电光调制器,产生可变多音抽运光,实现光边带多频同时处理。阻带个数、阻带中心频率和阻带带外抑制比均由射频信号调控。实验结果表明,该微波光子滤波器频谱响应呈非周期性,各阻带中心频率互不相干且与阻带个数无关,并可在2～8 GHz范围内独立调谐。阻带带外抑制比最大为49 dB。
Based on the stimulated Brillouin scattering, a variable multi-stopband microwave photonic filter with aperiodic spectral response is designed and experimentally demonstrated. Variable multi-tone pump light is generated and the multi-frequency optical sideband is simultaneously processed by the usage of a programmable electrooptic modulator driven by the radio-frequency signal. The number of stopbands, central frequencies of stopbands and out-of-band rejections of stopbands are controlled by the radio-frequency signal. As the experimental result shows, the spectral response of this microwave photonic filter is aperiodic, and the central frequencies of all stopbands are mutually uncorrelated and irrelevant with the number of stopbands, which can be tuned within 2 GHz to 8 GHz independently. The maximum out-of-band rejection can reach to 49 dB.
