利用表面等离子体激元对两平行金属板间缝隙宽度的依赖性，可以制作纳米光波导。这种波导可以被称为表面等离子体激元间隙波导（SPGW）。考虑了由SPGW构成的H面和E面光路。对由直的和分支的弯曲SPGW组成的纳米光路进行了三维数值模拟。结果表明，本文中考虑的光路可以在纳米器件中执行光波的引导、分支和弯曲功能。(C)2003年，美国物理学会。
Nanometric optical waveguides can be made by using the dependence of surface plasmon polaritons on the gap-width between two parallel metallic plates. This waveguide can be called surface plasmon polariton gap waveguide (SPGW). The H-plane and E-plane optical circuits that consist of SPGWs have been considered. Three-dimensional numerical simulations have been performed for the nanometric optical circuits that consist of straight and branched bend SPGWs. Results show that optical circuits considered in this letter can perform guiding, branching, and bending functions of optical waves in the nanometric device. (C) 2003 American Institute of Physics.
