"WebSep 1, 2024 · We study a novel family of mth-order cosine Gaussian optical vortex beams with an infinite (but countable) number of screw dislocations, each with the topological charge m. An expression is derived for the normalized-to-power orbital angular momentum (OAM) of such beams. The OAM is shown to increase quadratically with the order m.

WebA pair of stable noncanonical scalar vortices of the same charge is generated experimentally across the cross section of an optical beam using a computer-generated hologram with higher-order fractional screw dislocation. An optical vortex (also known as a photonic quantum vortex, screw dislocation or phase singularity) is a zero of an optical field; a point of zero intensity. The term is also used to describe a beam of light that has such a zero in it. The study of these phenomena is known as singular optics.
