摘要
光纤结构光场作为光场调控的一个重要分支,逐渐引起了研究者们的广泛关注。首先基于光纤矢量模式理论,讨论了光纤中具有空间偏振/相位奇异特性的结构光场的产生机理;然后,介绍了光纤结构光场的产生方法,如长周期光纤光栅耦合法、光纤端面微结构法和轨道角动量转换法等;最后,介绍了光纤结构光场在超分辨成像、涡旋光通信、等离子针尖纳米聚焦和非线性频率转换等方面的一些典型应用。
Abstract
Fiber-based structured light fields, as an important branch of light field modulation, have gradually attracted much attention of researchers. First, based on the fiber vector mode theory, the generation mechanism of fiber-based structured light fields with spatial polarization/phase singularity is discussed. Then, the generation methods of fiber-based structured light fields, such as long-period fiber grating coupling method, fiber end face microstructure method, and orbital angular momentum conversion method, are introduced. Finally, some typical applications of fiber-based structured light fields in super-resolution imaging, vortex light communication, plasmonic tip nanofocusing, nonlinear frequency conversion and so on are presented.
