摘要/Abstract

摘要： 应用时域有限差分(FDTD)方法,通过数值模拟研究光在二维异质结光子晶体L型弯曲波导的传输特性.结果表明:在异质结光子晶体波导中能更好地对光进行控制;并且异质结光子晶体L型弯曲波导的传输效率较同质结光子晶体波导提高了6;~7;.计算结果为高度集成化的光子晶体波导器件,提供了一条新的设计思路和依据.

Abstract: The transmission characteristics of L-type waveguides system based on 2D heterostructure photonic crystals was studied by finite-difference time-domain ( FDTD) method. The results showed that it is better for controlling light transmission by introducing heterostructure in this system. In the L-type waveguide system, the transmission efficiency raises 6;-7; for the heterostructure photonic crystal, compared to that on homostructure photonic crystal. The studies provided a new design solution improving the efficiency of high-integration photonic crystals waveguide devices.
