提出了一种基于低速信号注入法布里-珀罗型激光二极管(FP-LD)的无本振全光混频技术,利用FP-LD的一个纵模和外部注入信号光的四波混频作用生成的边带锁定纵模产生光载射频信号。通过改变FP-LD的注入光信号强度和偏振态实现副载波频率可变,并根据FP-LD注入锁定特性分析实验结果得到的不同边模抑制比。实验中采用2.7,2.5,1.25 Gb/s非归零(NRZ)码注入FP-LD实现副载波频率分别为16.2,10.0,18.2和20.0 GHz的全光混频,测量16.2 GHz的副载波得到了10 kHz偏移处单边带相位噪声为-81.2,-87.7 dBc/Hz。 A non-local all-optical mixing technique based on low-speed signal injection Fabry-Perot laser diode (FP-LD) is proposed. By using one longitudinal mode of FP-LD and four-wave mixing of external injected signal light The generated sidebands lock the longitudinal mode to produce an optical carrier RF signal. The subcarrier frequency can be varied by changing the intensity and the polarization state of the injected optical signal of the FP-LD, and the different side mode rejection ratios obtained from the experimental results are analyzed according to the FP-LD injection locking characteristics. Experiments using 2.7, 2.5, 1.25 Gb / s non-return to zero (NRZ) code into FP-LD to achieve sub-carrier frequencies were 16.2,10.0,18.2 and 20.0 GHz, all-optical mixing, The single-sideband phase noise at the 10 kHz offset is -81.2, -87.7 dBc / Hz.
