中文摘要：

采用三维时域有限差分算法（3D-FDTD）对GaAs/AlGaAs量子阱红外探测器（QWIP）的顶部光子晶体光输入耦合层结构的电磁场分布进行了仿真分析,得到了多种不同周期、占空比、深度的二维光子晶体结构耦合效率及电磁场分布.探索了一种双色探测器的光子晶体光输入耦合层结构的设计思路,使之可对中波/长波或长波双色8/12μm同时提供较高的耦合效率.

英文摘要：

Finite difference time domain （FDTD） method is used for the simulation and analysis of electromagnetic field in the top coupling layer of GaAs/AlGaAs quantum well infrared photodetector （QWIP）. Simulation results demonstrated the coupling efficiencies and distributions of electromagnetic （EM） field in a variety of 2D photonic crystal coupling layer structures. A photonic crystal structure for bi-color-QWIP is demonstrated with high coupling efficiency for two wavelengths.
