摘　　要：综述了近几年来亚波长陷光结构Hg Cd Te红外探测器研究进展.系统介绍了一种结合有限元方法与时域有限差分方法对红外探测器的"光""电"特性进行联合模拟和设计方法,以及基于这种新的数值模拟方法对亚波长人工微结构Hg Cd Te红外探测器的模拟和分析结果.理论分析和实验研制数据均显示这种新型亚波长人工微结构结构具有很好的陷光特性,在提高长波红外探测器性能方面具有潜在应用前景.Recent progress of Hg Cd Te infrared detector with subwavelength photon trapping structure has been reviewed in this paper. A combination approach of finite element method and finite difference time domain method,which can be used for jointly simulating of ＂ light＂ and ＂ electricity ＂ characteristics in infrared detector,was systematically introduced. Numerical simulation and analysis results based on the Hg Cd Te infrared detectors with subwavelength microstructure were also demonstrated. The theoretical analysis and experimental data have shown that the subwavelength microstructure can trap photons in active region of infrared detectors. The subwavelength photon trapping structure has a promising prospect on improving the performance of long wavelength infrared detector.
