实验证明了一种基于市售体材料电吸收调制器的短脉冲发生器。通过优化色散补偿光纤的长度，获得了接近变换极限的脉冲。有一个2 ps的脉冲序列与650 fs的定时抖动和10 GHz的重复率与两级非线性压缩获得。通过4×10 Gbit/s光时分复用（OTDM）通信系统实验进一步验证了脉冲质量，实现了0.3dB的低解复用功率代价。
A short pulse generator based on a commercially available bulk material electroabsorption modulator was experimentally demonstrated. By optimizing the length of the dispersion compensation fibre, nearly transform limited pulse was generated. There are a 2-ps-pulsed train with a timing jitter of 650 fs and a repetition rate of 10 GHz obtained with two-stage nonlinear compression. The quality of the pulse was further verified by 4×10 Gbit/s optical time-division-multiplexed (OTDM) communication system experiment in which a low demultiplexing power penalty of 0.3 dB was achieved.
