（1）概述

近些年来，太赫兹科学与技术作为一门持续发展的前沿学科，也吸引了越来越多的关注。太赫兹波具有的许多独特性质，在安全检查、物质鉴别和超高速无线通信等领域拥有很好的应用前景。对太赫兹光场的振幅、偏振态、位相、相干结构等进行空域调控，能够产生具有特殊空间分布的新型光场，这些新型空间结构光场展现了众多新颖的物理效应和现象。通过调控获得的新型太赫兹结构光场在通信，成像，无损探测等方面具有重要的应用。本人的相关工作主要集中在对太赫兹波的振幅和相位进行调控，产生具有涡旋结构的光场。产生的太赫兹涡旋结构光场，其兼有大带宽和增加一个通信自由度的特性，有希望极大地提高通信系统的容量和频谱的利用效率。
