该通信报告了一种简单的配置，用于实现一个紧凑的和全光纤为基础的宽度可调脉冲发生器，使用四波混频（FWM）的效果，只有1.9米的氧化铋为基础的高度非线性光纤（Bi-HNLF）。在重复频率为5和10 GHz的情况下产生了宽度可调谐的脉冲。在所进行的实验中，5GHz重复率脉冲串的脉宽从83 ps调谐到23 ps，而10 GHz重复率脉冲串的脉宽从32 ps连续调谐到18 ps。提出了一种可调脉宽脉冲产生的解析模型，其结果与实验结果吻合较好。讨论了泵浦源定时抖动和光强起伏对脉冲产生的影响。
This communication reports a simple configuration for the implementation of a compact and all-fiber based width-tunable pulse generator using four-wave mixing (FWM) effect in only 1.9-m of bismuth oxide based highly nonlinear fiber (Bi-HNLF). The width- tunable pulses are generated at repetition rates of 5 and 10GHz. In the performed experiment, the pulsewidth of a 5GHz repetition rate pulse train is tuned from 83 to 23ps whereas the pulsewidth of a 10GHz repetition rate pulse train is continuously tuned from 32 to 18ps. An analytical model is presented for width-tunable pulse generation and the results agree well with the experimental findings. The effects of pump source timing jitter and intensity fluctuation on pulse generation are discussed.
