Super pulses of orbital angular momentum in fractional-order spiroid vortex-beams

Abstract

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.
