A. V. Volyar, Yu. A. Egorov

摘要:

本文研究了具有螺旋状光强和相位分布的超几何高斯光束组合的光学特性。它们的轨道角动量作为分数阶拓扑荷的函数,具有一系列超脉冲(爆发和下降),超脉冲的形式可以通过螺旋参数来控制。这种现象可用于光学器件和通信系统的光学开关和触发器。

英文摘要:

We consider optical properties of Hypergeometric-Gaussian beam compositions with spiral-like intensity and phase distributions that were called the spiroid beams. Their orbital angular momentum as a function of a fractional-order topological charge has a chain of supper-pulses (bursts and dips).The form of the supper-pulses can be controlled by the spiral parameters. Such a phenomenon can be used in optical switches and triggers for optical devices and communication systems.
