基于表面等离子体效应的光开关研究现状和进展

Optical switches based on surface plasmons

摘要: 目前表面等离子体(surface plasmons, SPs)效应在光传感、光存储及生物光子学等领域的应用前景受到了广泛关注，通过计算模拟或实验基于SPs效应的光开关也层出不穷.文章较为系统地介绍了各种基于SPs效应的光开关原理和优缺点，对SPs全光开关做了重点介绍.

Abstract: Great attention is being paid to surface plasmons (SPs) because of their potential applications in sensors, data storage and bio-photonics. Recently, more and more optical switches based on surface plasmon effects have been demonstrated either by simulation or experimentally. This article describes the principles, advantages and disadvantages of various types of optical switches based on SPs, in particular the all-optical switches.
