An experimental study on the wavelength demultiplexing technology
摘要
文章提出一种基于光折变晶体LiNbO3的波分解复用技术实验研究方法, 研究了影响光栅衍射效率的重要因素。实验采用o光写入e光读出, 写入光强比为1∶1。通过在同一位置由红光和绿光先后写入光栅(两光栅夹角为0.18°时不会发生串扰), 并用耦合光读出, 成功地进行了解复用实验。
Abstract
This paper proposes an experimental research method for the wavelength demultiplexing technology that is based on volume holographic grating in photorefractive LiNbO3 crystal and studies the important factors that affect the grating diffraction efficiency. In this experiment, o-ray optical write in and e-ray readout are used when the write-in beam intensity ratio is nearly 1∶1. The experiment is successfully performed by writing into the grating in the same location with red and green lights successively and then reading out with coupled light. No interferences occur when the included angle between the two gratings is 0.18 °.
