本文用精确解麦克斯韦方程组的方法研究了亚波长直径石英和硅线的单模光波导特性。研究了单模条件、模场、功率分布、群速度和波导色散。结果表明，空气包层亚波长直径线具有紧约束能力、增强的倏逝场和大的波导色散等特性，这些特性对于开发未来的亚波长结构的微光子器件具有重要的应用前景。(C)2004年美国光学学会。
Single-mode optical wave guiding properties of silica and silicon subwavelength-diameter wires are studied with exact solutions of Maxwell's equations. Single mode conditions, modal fields, power distribution, group velocities and waveguide dispersions are studied. It shows that air-clad subwavelength-diameter wires have interesting properties such as tight-confinement ability, enhanced evanescent fields and large waveguide dispersions that are very promising for developing future microphotonic devices with subwavelength-width structures.
