摘要

利用时域有限差分方法对二维三角介质柱光子晶体的传输特性进行了研究

计算了不同晶格、同一晶格柱体截面面积不同、放置方位角不同、入射波入射方向不同时光子晶体的传输特性。结果表明:光子禁带的宽度与中心频率和晶格结构有很大关系

三角晶格更易形成平坦光子禁带

柱体截面面积大

则形成的禁带较宽

在其他因素相同的条件下柱体放置的方位角在一定范围内对光子禁带有重要影响;对不同入射方向时光子晶体的传输特性的研究结果表明

在低频范围内

入射角对禁带宽度和中心频率没有任何影响

在高频段

透射率随入射角变大而降低。研究结果为实验上制作三角柱光子晶体器件提供了重要的理论依据。

Abstract

The transmission properties of two-dimensional photonic crystals with triangular dielectric rods were studied using the finite difference time domain (FDTD) method for different lattice structures

section areas

azimuth angles and incident angles. The results showed that the photonic band gap (PBG) width and the central frequency depends on the lattice structure and sectional areas. Azimuth angle of cylinder affects the PBG in some degree

however the widths of band gaps are the same when their effective incident section are equal

such as with the

value of 0° or 60°. In addition

transmission characteristics have no changes with the variation of incident angle in range of low frequency (below 0.26

a/λ

)

but the transmission coefficient decreases dramatically with increasing frequency(0.28

a/λ

~0.37

a/λ

)

even new wider forbidden band is formed under certain conditions. This work will be of significance in fabricating PC devices.
