| 摘 要： | 采用一种基于法布里-珀罗腔激光二极管(FP-LD)的副载波信号的产生方案,此方案主要包括一个FP-LD和一个电光相位调制器(PM)。首先利用可调谐激光器、电光PM及微波源产生光正弦相位调制信号,将该信号注入到FP-LD中,通过FP-LD的注入锁定将该信号转换为副载波信号。在实验中,分别以2、3、4和5 GHz的调制频率注入到FP-LD中,相应得到22、21、24和25 GHz的副载波信号。

| Abstract: | In this paper,a convertion scheme of subcarrier frequency modulation signal is proposed based on Fabry-Perot cavity laser diode(FP-LD),including an FP-LD and an electro-optic phase modulator(PM).First of all,the sinusoidal phase modulation optical signal is obtained by the tunable lasers,electro-optic phase modulator and microwave source,then the phase modulated optical signal is injected into the FP-LD,and the low frequency phase modulated signal is convered into the subcarrier frequency modulation signal based on injection-locking in the FP-LD.In the experiment,the optical signals with 2 GHz,3 GHz,4 GHz and 5 GHz modulation frequencies are injected into the FP-LD,appropriate to be 22 GHz,21 GHz,24 GHz and 25 GHz subcarrier FM signal,respectively. |
