摘要
基于光注入法布里-珀罗(F-P)激光器的波长选择性放大理论,设计并实现了一种窄带可调谐的单通带微波光子滤波器(MPF)。通过改变注入锁定参数,研究了注入锁定参数对中心频率、插入损耗和带外抑制比等性能指标的影响,以及波长功率放大与腔模红移的关系。实验结果表明,通过合理调节注入功率比、主从激光器失谐频率和偏置电流,可以获得带外抑制比为27.9dB、3dB带宽为275 MHz和调谐范围为9~32GHz的MPF。所提结构可以应用于高频、宽带可调谐的滤波选频和光电振荡。
A narrow single pass band tunable microwave photonic filter(MPF)is designed and experimentally demonstrated based on the theory of wavelength-selective amplification of Fabry-Perot(F-P)laser with optical injection.Through changing the injection locking parameters,we investigate the influences of injection locking parameters on the the central frequency,insertion loss,and out-of-band suppression ratio,and the relationship between the wavelength power amplification and the cavity mode red-shift.The experimental results show that,when the injection power ratio,detuning frequencies of the master slave lasers and bias current are properly adjusted,the out-of-band suppression ratio of MPF is 27.9 dB,the 3 dB passband is 275 MHz and the frequency of MPF can be tuned from 9 GHz to 32 GHz.The proposed structure is useful for applications such as filters frequency selection and optic-electric oscillation,where require high frequency and wideband tunability.
