复杂光场：突破极限 Breaking Limits with Complex Optical Fields

报告摘要：

近来具有空间可变振幅，位相和偏振分布的复杂光场吸引了越来越多的研究兴趣。其中携带轨道角动量的标量光涡流和径向角向偏振光得到最为广泛的关注。这些光场横截面上的振幅，位相和偏振的多样性使得光学工作者在光学和光子学方面突破传统极限成为可能。利用复杂光场的新的应用以及市场化的产品不断涌现。本报告将为广大听众介绍此一领域的基础及其在光焦场调控，光刻，激光微加工，显微成像，微纳粒子操控，光学计量表征，光通信，量子光学等领域最新的应用。

Recently there is an increasing interest in complex optical fields with spatially variant amplitude, phase and/or polarization within the beam cross-section. Scalar optical vortices carrying orbital angular momentum and vectorial vortices such as radially, azimuthally polarized beams are among the most intensively studied examples. The added degrees of freedom arising from the amplitude, phase and polarization diversity within the beam cross-section enables scientists and engineers to break the limits imposed by conventional wisdom in many optical and photonic applications. Applications of these complex optical fields in many promising areas and new commercial products continue to emerge. This talk aims to serve as an introduction of the fundamentals and applications in this field to broad audience.
