Abstract

This paper present a six port PCWG channel created from a circular photonic crystal array (CPC) with filtering functions. PC based waveguide (PCWG) created along the radial direction of CPC enables the transmission of lightwaves in subwavelength width structures. Additional filter rods are added to the PCWG to server as filtering function so that only allowed lightwaves with designated frequency can pass through the rods set. The other frequencies will be reflected. This PC device allow the distribution of light for different frequencies to different output port channel, which is very useful for multiplexing optical circuit and system.
基于圆形光子晶体的六端口波导滤波器
提出了一种具有滤波功能的圆形光子晶体阵列(CPC)的六端口PCWG通道。基于PC的波导(PCWG)沿着CPC的径向方向创建,可以在亚波长宽度结构中传输光波。在PCWG中添加额外的滤光棒作为过滤功能,以便只允许具有指定频率的光波通过该滤光棒集。其他频率将被反射。该PC器件允许将不同频率的光分配到不同的输出端口通道,这对于多路复用光电路和系统非常有用。
