摘要

在二维三角光子晶体环形腔的周围增加六个散射介质柱

构成一个新的环形腔结构

该结构使光波的透射率达到90%

带宽也比较小。通过改变光子晶体介质柱的折射率

使环形腔的选择波长不断改变

能够明显地区分出两个不同波长

且分波波长在通信波长范围之内。将不同折射材料的光子晶体连接在一起

构成一种新的光子晶体波分复用器

相比同种材料

它具有高效率

多波长选择的优点。利用这种异质结构可以构建一个多波长的波分复用结构

它也为制作多通道波分复用器奠定了基础。

Abstract

Six scatters is increased in two-dimensional triangular photonic crystal ring resonator

forming a new ring-cavity structure

so that the transmission of light waves attain 90%

the bandwidth is relatively small in the optimized ring resonators. By changing the refractive index of photonic crystals dielectric cylinders

but also the selection of ring cavity wavelength is changed

so discriminate clearly two different wavelength

the wavelength of partial wave is the range of the communication wavelength. Different refractive materials of photonic crystals connected together to form a new kind of photonic crystal WDM

compared with the same kinds of material

which has the advantages of high efficiency and multi-wavelength selection. This heterogeneous structure can be used to build a multi-wavelengths structure

it is also the foundation for the facture of multi-channels WDM device.
