Abstract:
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.
