摘要

利用体相位全息光栅的优良特性,研制光栅式密集型波分复用器(DWDM)。准直后的信道波长通过体相位全息光栅两次衍射,在焦面上实现信道波长的分复用。阐述了体相位全息光栅的独特结构特点,给出了体相位全息光栅式密集型光波分复用器件的原理图,计算出各个信道的位置及间隔,用Zemax仿真出设计模型。相比于薄膜滤光片式器件而言,具有许多独特的优良特性,能够实现更密集更多信道数量的分复用。

Abstract

Based on volume phase holographic grating's quality character,a type of wavelength division multiplexing was developed. Collimated channel waves were diffracted by double passing a grating,then resulted in wavelength multiplexing on the collimated lens's focal plan. The unique characteristic of the VPH grating and the principle figure of multiplexing device were introduced. Every channel's position and interval were calculated. The device was designed by Zemax soft. Its characters were analyzed. Based on the thin film filter,the device has more unique advantages and can achieve denser and more channels.
