论文摘要
时空光学涡流（STOV）是一种独特的光学涡流，在时空域中具有相位奇异性，而STOV中的光子可以携带横向轨道角动量（OAM）。 STOV展示了许多值得探索的奇妙属性。在这里，我们从理论上和实验研究StoV的衍射特性，这是一种基本波浪现象。 STOV的衍射行为显然受横向OAM的影响。通过光栅衍射的STOV脉冲的衍射模式显示多叶结构，每个间隙对应于1个拓扑电荷。清楚地证明了带有横向OAM的光的衍射特性，并帮助我们理解STOV的物理特性，STOV将是特殊应用的，例如实现具有不同拓扑电荷的STOV的快速检测，这可能为基于STOV的基于STOV的光学通信付出了道路。
Spatiotemporal optical vortex (STOV) is a unique optical vortex with phase singularity in the space-time domain and the photons in a STOV can carry transverse orbital angular momentum (OAM). The STOV shows many fantastic properties which are worth exploring. Here, we theoretically and experimentally study the diffraction property of STOV, which is a fundamental wave phenomenon. The diffraction behaviors of STOVs are obviously affected by the transverse OAM. The diffraction patterns of STOV pulses diffracted by a grating show multi-lobe structure with each gap corresponding to 1 topological charge. The diffraction properties of lights with transverse OAM are demonstrated clearly and help us understanding the physical properties of STOV, which will be of special applications, such as the realization of fast detection of STOVs with different topological charges, which may pay the way for STOV based optical communication.
