表面等离子体激元(SPPs)是通过改变金属表面的亚波长结构实现的一种光波与可迁移的表面电荷之间电磁模,可以用来从而传输光能量,且不受衍射极限的限制。正因为SPPs这种独特的性质,使其在纳米量级操纵光能量发挥着重要的作用。当前已经产生了以SPPs研究为核心内容的亚波长光学这一学科,科学家们对此进行了广泛的研究,提出了各种的器件与机理。本文以亚波长尺度的波导结构为基础,从当前发展的较为成熟多种波导结构、应用情况对传导型表面等离子体激元的传播的研究进行了回顾和讨论,旨在将这一领域相关研究成果及发展方向展示给读者。
Surface Plasmon Polaritons (SPPs) are electromagnetic modes between a light wave and a migratable surface charge by changing the subwavelength structure of the metal surface, which can be used to transmit light energy without being limited by the diffraction limit. Because of the unique nature of SPPs, SPPs play an important role in manipulating light energy at the nanometer scale. Nowadays, the subwavelength optics with SPPs research as the core has been produced. Researchers have conducted extensive research and proposed various devices and mechanisms. Based on the subwavelength waveguide structure, this paper reviews and discusses the propagation of the conducted surface plasmon polariton from the current more developed and widely used waveguide structures and applications. The purpose of this paper is to review the related research in this field The results and development of the show to the reader.
