实验证明了一种基于表面等离子体激元晶体(SPPC)的紧凑型四能级偏振鉴别器。它能够唯一地分辨并在空间上分离已经在0度、45度、90度和135度方位角上线性极化的四个信号。它利用了SPPC在单色光照射下在非简并方向上的多个表面等离子激元本征模的激发。该器件是平面的，具有微米级的尺寸，适合于光子电路的片上集成和小型化。(C)2011年美国物理研究所。[DOI：10.1063/1.3561748]
A compact, four-level polarization discriminator based on a surface plasmon polaritonic crystal (SPPC) has been experimentally demonstrated. It is able to uniquely resolve and spatially separate four signals that have been linearly polarized at azimuth angles 0 degrees, 45 degrees, 90 degrees, and 135 degrees. It exploits the excitation of multiple surface plasmon polariton eigenmodes in nondegenerate directions when the SPPC is illuminated with monochromatic light. The device is planar and of micrometer scale, which makes it suitable for on-chip integration and miniaturization of photonic circuits. (C) 2011 American Institute of Physics. [doi:10.1063/1.3561748]
