摘要

采用平面波展开法(PWM)和时域有限差分(FDTD)法,研究光在含点缺陷的光子晶体波导中的传输特性.计算结果表明,通过引入两共振腔(点缺陷),处于共振频率附近的光波将被完全反射回光子晶体波导.由于共振频率随点缺陷的折射率的变化而改变,这种现象可用来设计可调光开关.

The transmission characteristics of a 2D photonic crystal waveguide with point defects were investigated by the plane wave expansion method (PWM) and finite difference time domain (FDTD) method. It was found that by introducing two resonant cavities (point defects) in the photonic crystal waveguide, light waves near the resonance frequencies can be totally reflected back to the waveguide. Since the resonance frequencies change with the variation of the refractive index of point defects, this phenomenon may be used to design a tunable optical switch.
