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

We have experimentally created perfect optical vortices by the Fourier transformation of holographic masks with combination of axicons and spiral functions, which are displayed on a transmission liquid crystal spatial light modulator. We showed theor

In atmospheric turbulence, relative humidity has been almost a negligible variable due to its limited effect, compared with temperature and air velocity, among others. For studying the horizontal path, a laser beam was propagated in a laboratory room

We report on a novel experimental geometry to generate cylindrical vector beams in a very robust manner. Continuous control of beams’ properties is obtained using an optically addressable spatial light modulator incorporated into a Sagnac interfero

La naturaleza periódica de las imágenes de tejido textil permite el uso de las técnicas de la transformación de Fourier rápida para su clasificación. Debido a los patrones de repetición dentro de las imágenes del tejido textil, es posible enc

The phase shift induced on a Gaussian beam interacting with a nonlinear medium determines the far field diffraction pattern characteristics. It is usual to consider that the induced phase shift by a nonlinear media is due only to the effects of the r
