Abstract

We consider optical properties of hypergeometric-Gaussian beam compositions with spiral-like intensity and phase distributions called spiroid beams. Their orbital angular momentum as a function of a fractional-order topological charge has a chain of super-pulses (bursts and dips). The form of the super-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.
