摘要

本文报道了在亚波长金属谐振腔的超材料阵列中工作的红外探测器的最新进展。金属超材料谐振腔由于其强大的局部场增强和天线效应的结合，对高温探测器的性能有一定的影响。后者允许从一个比设备的电区域大得多的区域收集光子，从而大大减少热激发探测器的暗电流。

Metamaterial-Enhanced Quantum Infrared Detectors

Recent advances on infrared detectors that operate in metamaterial arrays of sub-wavelength metallic resonators are reported. The metallic metamaterial resonators have a quantitative impact on the high temperature detector performance, owe to the combination of a strong local field enhancement and an antenna effect. The latter allows collecting photons from an area that is much larger than the electrical area of the device, resulting in a strong reduction of the thermally excited detector dark current.
