最近预测，延迟干扰信号波长转换器 (DISC) 中小子脉冲的生成是一个潜在问题，该转换器已被研究用于未来 160 Gb/s 光时分复用 - 波分复用 (OTDM-WDM) 通信系统。在这项工作中，我们通过实验验证了这种脉冲的产生及其机制。在实验中，我们使用了重复频率为 12.5 至 25.0 GHz 的 3.8 ps 长 1.56 µm 输入脉冲以及时间分辨率约为 2 ps 的互相关监测系统。
The generation of small sub-pulses in the delayed-interference signal-wavelength converter (DISC), which has been studied for use in future 160-Gb/s optical time division multiplexing–wavelength division multiplexing (OTDM–WDM) communication systems, was recently predicted as a potential problem. In this work, we have experimentally verified the generation of such pulses and its mechanism. In the experiments we used 3.8-ps-long 1.56-µm input pulses with repetition frequencies from 12.5 to 25.0 GHz and a cross-correlation monitoring system with a time resolution of approximately 2 ps.
