ABSTRACT
本研究分析了目前量子阱红外探测器应用中的主要制约因素,从表面等离子体的激发和传输物理机制出发,将表面等离子体近场光增强效应引入量子阱红外探测器光栅设计中,通过模拟计算进一步分析了光栅结构参数对探测器吸收波长和强度的影响,为未来这项技术的进一步应用打下理论基础。In this paper, the main restricting factors of quantum well infrared detector application were analyzed. Through studying on the physical mechanism of surface plasmon excitation and transmission, we developed a surface plasmon grating for quantum-well infrared detector. The influence on transmission intensity and wavelength with the constructor parameters of grating was discussed. The result is giving theoretical basis for future quantum well infrared detector application.
