我们实验证明了一种新的脉冲压缩方案，使用色散递减光纤（DDF）为基础的分布式拉曼放大。我们在一个20公里的基于ddf的二极管泵浦拉曼放大器中，绝热压缩使用市售电吸收调制器产生的10 ghz 13ps种子脉冲为高质量的1.3 ps脉冲。通常的DDF绝热孤子压缩过程是由沿光纤分布的拉曼增益和输入脉冲啁啾控制辅助的。波长可调性约为30 nm，脉宽可调性为1 ~ 5 ps。
We experimentally demonstrate a novel pulse compression scheme using dispersion decreasing fiber (DDF)-based distributed Raman amplification. We adiabatically compress 10-GHz 13-ps seed pulses generated using a commercially available electroabsorption modulator into high-quality 1.3-ps pulses in a 20-km DDF-based diode-pumped Raman amplifier. The usual DDF adiabatic soliton compression process is assisted by the distributed Raman gain along the fiber and by control of the input pulse chirp. Both wavelength tunability of about 30 nm and pulse-duration tunability from 1 to 5 ps are also demonstrated.
