摘要

光电探测器可以实现光信号到电信号的转换，在工业、军事、医疗等领域已展现出巨大的应用价值。但是，传统的平直型光电探测器捕获线光的能力较弱，一定程度上限制了响应率等性能指标的进一步提高。而基于贵金属纳米结构的表面等离激元共振可以急剧增强近场区域的(纳米尺度)电场强度和对线光的捕获能力，大幅度地提高光电探测器性能。本文首先介绍了表面等离激元的基本原理。随后，详细介绍了金属纳米颗粒、金属光栅等不同结构的表面等离激元增强型光电探测器研究进展。最后，总结全文并针对表面等离激元增强型光电探测器的发展前景做出了展望。

Abstract

Photodetectors can realize the conversion of optical signal to electrical signal

and have shown great application value in the fields of industry

military

medical treatment and so on. However

the traditional flat photodetector has a weak ability to capture line light

which limits the further improvement of responsiveness and other performance indicators to a certain extent. Surface plasmon resonance effect based on noble metal nanostructure can dramatically enhance the electric field intensity in the near field region and strengthen the ability of the photodetector to capture the line light

thus greatly improve the performance of photodetector. In this paper

the basic principle of surface plasmons is introduced at first. Then

the research progress of surface plasmon enhanced photodetectors with different structures

such as metal nanoparticles and metal gratings

is introduced in detail. Finally

the thesis is summarized and the development prospect of surface plasmon enhanced photodetectors is put forward.
