摘要
给出一个单一器件同时具有分波器和大规模分束器功能的实验结果 ,其设计原理基于塔尔博特自成像效应。以两波长为例 ,通过改变分数塔尔博特距离和光栅周期等参量 ,实验上实现了两波长光信号在空间上的交叉分离。
The experimental results that a single element based on the Talbot self-imaging effect realizing both beam splitting and wavelength-division multiplexing functions are presented. For the input beam with two wavelengths, and by designing the parameters such as grating period and the fractional Talbot distance, the interleaved self-images in space of a grating corresponding to two wavelengths can be exactly observed in the experiment.
