Surface plasmon polaritons-based integrated nanophotonic devices

  • 摘要: 纳米集成光子学的核心关键技术之一在于新型高效纳米光耦合器、纳米光波导等纳米光子器件的设计与制备.表面等离子体激元(SPPs)是由外部电磁场与金属表面自由电子相互作用形成的一种相干共振,除具有巨大的局部场增强效应外,还具有将激发电磁场能量限制在纳米尺度范围的特点.基于SPPs的各种纳米光子器件被誉为当今最有希望的纳米全光集成回路的基础,成为目前国际上的一个研究热点.文章对基于SPPs的纳米集成光子器件的最新研究进展和研究成果进行评述.

     

    Abstract: One of the crucial technologies for integrated nanophotonics is the design and implementation of novel and high efficiency nanocouplers, nanoguides and other related optical components. Surface plasmon polaritons (SPPs) are a coherent oscillation of free charges in the surface of metals in resonance with the incident light wave, which have the distinguishing capabilities of enhancing the local electric field intensity as well as of confining the optical energy within the nanoscale domain. As one of the most promising candidates for nanophotonic circuits SPP-based nanoscale optical devices have attracted enormous interest in recent years. In this article we present an overview of the progress in research on the fabrication of SPP-based integrated nanophotonic components.
