摘要

传统的WDM（波分复用器）通常尺寸较大

这一缺陷成了光子集成化的"瓶颈"。文章利用光子晶体的多模干涉效应设计了一种光子晶体三波长（1 310、1 490和1 570nm）WDM。仿真结果表明

该器件对3个波长的插入损耗均!0.45dB

通道隔离度均"15dB;且尺寸仅为37#m$13#m

易于光学集成

性能优良。

Abstract

The conventional WDM are usually large in size

which has become the bottleneck of the photonic integration.This paper designs a type of three-wavelength（1 310nm

1 490nm and 1 570nm）photonic crystal WDM by utilizing the multimode interference effects of photonic crystals.The simulation results show that the insertion loss of this device for the three wavelengths is all less than 0.45dB

and the channel isolation is all larger than 15dB.In addition

its size is only 37#m $13#m.easy to be optically integrated and superb in performance.
