摘要

运用时域有限差分方法分析了二维液晶-金属光子晶体波导的光学特性。二维正方晶格金属光子晶体波导位于两个电极之间

其背景介质为液晶。通过在电极上施加不同电压

电场诱导液晶取向以改变液晶的折射指数从而改变光子晶体的带隙结构。数值计算结果表明:通过外界电场控制所填充的向列相液晶的方向可以对这种金属光子晶体波导的光学特性进行调节

该波导可用于制作光子晶体光开关等光学器件。

Abstract

The optical properties of a 2D liquid crystal-metal photonic crystal waveguide is analyzed with the FDTD method. A 2D square lattice metal photonic crystal waveguide lies between two electrodes filled with liquid crystal. By introducing different voltages to the electrodes

the orientation of the liquid crystal can be induced thus to change the refractive index of the liquid crystal

which varies the band structure of the photonic crystal. Numerical results show that the optical properties of the metal photonic crystal waveguide can be modulated by the voltage adjustment. This photonic crystal waveguide can be used in making optical switches and other optical devices.
