纳米光学天线研究现状及进展

基于spp共振效应的纳米天线结构能有效收集光的能量，并将它限制在亚波长尺度，其巨大的局域场增强效应为纳米光子学大范围的应用提供了广阔的前景，例如，纳米尺度内光信息的处理和传播、近场显微镜超分辨率成像、高效太阳能电池、超高密度近场光存储、纳米光刻、量子单光予源、高效率纳米电磁波集中器、高灵敏度生化传感器等。文章在介绍纳米天线的基本构造和工作原理的基础上，综述了其在多个领域的应用。

Research Status and Development of Nano-optical Antenna

Nanoantenna structure based on Surface Plasmon Polariton resonance effect can efficiently collect light energy and confine it to a subwaveleugth volume. The strong localized, enhanced field provides a broad prospect for wide nano- photonics applications, It can be exploited in many fields, such as optical information processing and propagating on nanometer scale, super-resolution near-field microscopy imaging,highly cost-efficient solar cells,ultrahigh density near-field optical storage, nanolithography,single quantum dots source,high-efficiency nano-electromagnetic wave collector,and high-sensitivity biochemical detectors.Based on the intrduction of the nanoantennas structure and principle, The paper summarize its application in many fields.
