研究了光在有限尺寸表面等离子激元（SPP）晶体上的光谱色散。角波长分离的一个或多个数量级高于其他国家的最先进的波长分裂装置可用的日期已被证明。两个阶段的过程负责色散值，其中包括将入射光转换为纳米结构的SPP Bloch模式，然后在SPP晶体边界处进行SPP Bloch波折射。在等离子体器件中实现的高光谱色散可能对纳米光子、光通信和芯片实验室应用中的集成高分辨率光谱有用。
Spectral dispersion of light on a finite-size surface plasmon polaritonic (SPP) crystal has been studied. The angular wavelength separation of one or more orders of magnitude higher than in other state-of-the-art wavelength-splitting devices available to date has been demonstrated. The two-stage process is responsible for the dispersion value, which involves conversion of the incident light into SPP Bloch modes of a nanostructure followed by the SPP Bloch waves refraction at the SPP crystal boundary. The high spectral dispersion achievable in plasmonic devices may be useful for integrated high-resolution spectroscopy in nanophotonic, optical communication and lab-on-a-chip applications.
