Title: 螺旋光：生成光学漩涡

Abstract: We experimentally generate optical tornado waves using spatial multiplexing on a single-phase modulation device. In their focal region, the intensity pattern outlines a spiral of decreasing radius and pitch. We examine the propagation dynamics of such novel waves and reveal the key factors that lead to angular acceleration. Moreover, we propose a two-color scheme that makes it possible to generate dynamically twisting light, an optical analog of a drill, that can rotate at THz frequencies. Show Chinese abstract

Abstract: 我们通过在单相调制设备上使用空间复用技术实验生成光学龙卷波。 在它们的焦区域，强度图案呈现出半径和螺距逐渐减小的螺旋形状。 我们研究了这种新波的传播动力学，并揭示了导致角加速度的关键因素。 此外，我们提出了一种双色方案，使得能够生成动态扭曲的光，这是一种钻头的光学模拟，可以在太赫兹频率下旋转。
