摘要

龙卷风波的特点是其独特的能力，加速和扭曲光在径向和角的尺寸。这些光束是通过操纵轨道角动量产生的，但探测它们的拓扑电荷一直是一个未知的领域。提出了一种基于离轴嵌入旋涡的圆形燕尾光束的新型龙卷风光束。我们分析了光的传播动力学，并采用交叉相位调制的方法测量了具有多个涡旋的圆形燕尾龙卷风光束的拓扑电荷。通过计算机模拟和实验观测，验证了该方法的可靠性。该技术为测量龙卷风光束中的拓扑电荷提供了一种省时、实用的解决方案。这一特性对光捕获的应用和光通信系统的发展是非常有益的。

Generation and topological charge detection of multiple-vortex circular swallowtail tornado beams

Tornado waves are characterized by their unique ability to accelerate and twist light in radial and angular dimensions. These beams are generated by manipulating orbital angular momentum, but detecting their topological charge has been an uncharted territory. This paper presents a novel Tornado beam based on off-axis vortices-embedded circular swallowtail beams. We analyze the light propagation dynamics and employ cross-phase modulation to measure the topological charge of this circular swallowtail tornado beam with multiple vortices. Our method has been confirmed through computer simulations and experimental observations, proving its reliability. This technique offers a time-efficient and practical solution for measuring topological charges within tornado beams. This feature is highly beneficial for applications in light trapping and the advancement of optical communication systems.

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
