Abstract Optical vortex beams are under considerable scrutiny due to their demonstrated potential for applications ranging from quantum optics to optical communications and from material processing to particle trapping. However, upon interaction with

Abstract Optical manipulation of colloidal systems is of high interest for both fundamental studies and practical applications. It has been shown that optically induced thermophoresis and nonlinear interactions can significantly affect the properties

The orbital angular momentum revolutionized optical communications, like an OAM beam of light need not be interrupted for the transfer of data, provides immunity to electromagnetic interference, allows increase bandwidth, rate and transmission capaci

This work develops a brief proposal to achieve the superposition of two opposite vortex beams, both with integer or non-integer mean value of the orbital angular momentum. The first part is about the generation of this kind of spatial light distribut

La carga topológica de una onda electromagnética CT, está relacionada con su distribucion espacial en el frente de onda. Ondas electromagnéticas con un factor acimutal exp(il) en su fase, tienen CT entera (l=m) o no entera (l=M). Estas ondas e

Upon interaction with inhomogeneous media, high-order optical vortices divide into canonical ones which diffuse away from the optical axis. We demonstrate how this dynamic process depends on both the topological charge and the interaction strength.

Laguerre–Gaussian (LG) beams are characterized by an azimuthal index or topological charge (m), associated with the orbital angular momentum, and by a radial index (p), which represents the number of the rings in the intensity distribution. We pres

We develop analytical expressions using the Fresnel diffraction theory of the spatial coherence function of speckle fields generated by scattering a Mathieu beam through a diffuser modelled as a delta correlated phase screen.

We develop an analytical model for the 3D spatial coherence function of speckle fields generated by scattering of vortex and perfect optical vortex beams. The model is general and describes the spatial coherence along both the transversal and the lon
