摘要

将纳米结构等离子体阵列应用于hgcdte红外探测器表面，可大大提高其中红外波段的吸收性能。阵列的周期性与表面等离子体-极化子固定模式的激发相结合，大大提高了吸收效率，从而减少了HgCdTe的吸收厚度。

Plasmonic nanorods for enhanced absorption in mid-wavelength infrared detectors

The absorption properties of HgCdTe-based infrared detectors can be greatly increased in the mid-infrared band, by incorporating nanostructured plasmonic arrays on the illuminated detector face. The array periodicity, combined with the excitation of surface plasmon-polariton stationary modes, enhances the absorption efficiency by a substantial amount, allowing to reduce in turn the HgCdTe absorption thickness.
