控制光信号在亚波长或纳米尺度的波导中传输对实现超紧凑的光子学器件和高密集的集成光路十分重要,因为它代表着集成光学向集成纳米光子学的迈进。人们已用光刻技术制作出基于金属材料的表面等离子体纳米波导、基于平面介质材料的纳米光子线波导、光子晶体波导等,也通过自组装等方法或技术制作出基于半导体材料或有机聚合物材料的纳米结构等。聚合物纳米线由于具有良 Controlling the propagation of optical signals in subwavelength or nanometer-scale waveguides is important for achieving ultra-compact photonic devices and high-density integrated optical paths, as it represents a move towards integrated optics toward integrated nanophotonics. Photolithography has been used to fabricate surface plasmonic nano-waveguides based on metallic materials, nano-photonic waveguides based on planar dielectric materials, photonic crystal waveguides, etc., and also to fabricate materials based on semiconductor materials or organic polymers Nanostructures and other materials.
