摘要

光场约束是光学科学与技术领域中备受关注的一个课题。在空间维度上对光波进行收缩和限制，不仅可以减小光波的足迹尺寸，而且可以大大增强光波在受限区域内的场强，从而增强光与物质的相互作用。这对于微光子学和纳米光子学来说特别有趣，因为人们通常喜欢在选定的方向上将场限制在波长以内。熟悉的例子有沿光纤或波导的倏逝场、局部等离子体的表面场增强、金属尖端的场增强

Optical waveguiding along nanometer slits

Optical field confinement is a topic of immense interest in optical science and technology. Shrinking and confining an optical wave in spatial dimensions not only reduces the size of its footprint, but greatly enhances its field strength in the confined region, leading to stronger light – matter interaction. This is particularly interesting for micro-and nano-photonics where one often likes to have fields confined to less than a wavelength in selected directions. Familiar examples are evanescent fields along optical fibers or waveguides, surface field enhancement of local plasmons, field enhancement on metal tips
