摘要

我们的研究表明，将两束正交偏振、突然自动聚焦、携带轨道角动量（OAM）的环艾里光束叠加在一起，就能产生像龙卷风一样螺旋上升的波恩卡莱偏振奇点。这些偏振奇点由与其中一个叠加光束的高强度环相适应的相同螺旋度的相位旋涡提供种子，沿着其传播轨迹以加速的方式扭曲和收缩。这些波恩卡龙卷风的角加速度超过 120 弧度/平方毫米，可应用于奇异光学、波前整形、偏振工程和复杂介质成像。

Poincaré tornados.

We show that Poincaré polarization singularities, spiraling like a tornado, can be generated by superimposing two orthogonally polarized, abruptly auto-focusing ring-Airy beams that carry orbital angular momentum (OAM). Seeded by phase vortices of the same helicity, which are adapted to the high-intensity rings of one of the superimposing beams, these polarization singularities follow trajectories that twist and shrink in an accelerating fashion along their propagation. Reaching angular acceleration that exceeds 120 rad/mm², these Poincaré tornados can find application in singular optics, wavefront shaping, polarization engineering, and imaging through complex media.

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
