型表面等离子体分光器的研究
he study on T shaped plasmonic splitter
提出了一种基于金属-绝缘体-金属（metal-insulator-metal, MIM）结构的T型表面等离子体分光器。该结构由一个T型波导和两个圆盘共振腔组成，其中一个共振腔内填充各向异性介质。利用时域有限差分法（Finite-Difference Time-Domain, FDTD）研究其分光特性。模拟结果表明，该结构可以实现双向分光的目的。分光器的分光波长受各向异性介质光轴的调制，随着光轴的旋转，向右方向的分光波长发生红移从705nm至828nm，而向左方向的分光波长基本保持在904nm不变。双向分光比均可达到10：1以上。
plamonic splitter based on a metal-insulator-metal (MIM) T shaped waveguide and two disk resonators is proposed. One of the disks is filled with anisotropic material. The splitting characteristic is simulated by using finite-difference time-domain (FDTD) method. The bidirectional splitting effect can be obtained. The splitting wavelengths can be manipulated by adjusting the optical axial angle of the anisotropic material. With the optical axis rotation, the splitting wavelengths of the right direction are red shift, which are from 705nm to 828nm. While the splitting wavelengths of the left direction remain the same, as 904nm. The bidirectional splitting ratios of our structures can be achieved up to 10:1.
