Abstract

The interaction between the chiral light and matter is vital to construct on-chip multi-functional photonic circuits. The well-known spin-orbit interaction has obtained significant attention in manipulation of light with different circular polarization states. We propose a robust Y-type surface plasmon nano-waveguide structure to effectively sort spin-dependent photons. The optimized simulation results demonstrated that the waveguide modes excited by circularly polarized light with different spin states can be selectively coupled to one of two branching waveguides, with a unidirectionality efficiency up to 0.95. This research may open up new ways for the on-chip implementation of complex photonic functions, nano-photonic circuits, and nano-optical manipulation.

利用 Y 型等离子纳米电路选择性分拣自旋光子

手性光与物质之间的相互作用对于构建片上多功能光子电路至关重要。众所周知的自旋轨道相互作用在操纵具有不同圆偏振态的光方面备受关注。我们提出了一种坚固的 Y 型表面等离子体纳米波导结构，可有效分拣自旋光子。优化模拟结果表明，不同自旋态的圆偏振光激发的波导模式可选择性地耦合到两个分支波导中的一个，单向性效率高达 0.95。这项研究为在芯片上实现复杂的光子功能、纳米光子电路和纳米光学操纵开辟了新的途径。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
