建议并通过实验证明了一种针对数十千兆赫处理带宽优化的全光纤光子时间微分器的新颖配置。该器件弥补了之前演示的两种全光纤设计（即基于光纤布拉格光栅的微分器（<20GHz）和基于均匀长周期光纤光栅的微分器（>100–200GHz））之间处理带宽的差距。
A novel configuration of all-fiber photonic temporal differentiator optimized for tens-of-gigahertz processing bandwidth is suggested and experimentally demonstrated. This device covers the gap in terms of processing bandwidth between the two previously-demonstrated all-fiber designs, namely the fiber Bragg grating-based differentiator (<20GHz) and that based on a uniform long-period fiber grating (>100–200GHz).
