The effect of source, geometrical and physical parameters of slab waveguide on the sensitivity of optical sensor and its evanescent field have been investigated. The waveguiding film of LiNbO3 was fabricated and the observations revealed that the max

In this paper, we analytically demonstrate the propagation of a useful structured light laser beam;namely, the vortex Laguerre-Gaussian beam, the latter is an eigenmode of free space propagation,which is invariant under propagation in lossless system

In this work, we present a detailed study of the on-axis intensitydistribution of the Laguerre-Gaussian beam with no azimuthal index,diffracted by an opaque disk, by means of numerical simulation ofFresnel-Kirchhoff diffraction integral. We investiga

Accelerating beams, of which the Airy beam is an important representative, are characterized by intensity maxima that propagate along curved trajectories. In this work we present a simple approach to directly generate accelerating beams with controll

The present paper investigates the spatial proprieties of a novel beam introduced recently known as Airyprime beam, its on-axis and transverse intensities are studied numerically. It is shown that the focused Airyprime beam exhibits two focuses corre

It has been known for some time that Bessel–Gaussian beams and their associated families self-heal after encountering obstacles. Recently, it has been shown theoretically and experimentally that radial mode Laguerre–Gaussian (LG) beams would like

In this paper, we propose a predictor or indicator of the self-healing ability of coherent structured light beams: the field's modal content. Specifically, the fidelity between the obstructed and unobstructed beams' modal spectrum serves as a useful

In this paper, we demonstrate the shaping of an incident Gaussian beam into a tunable hyperbolic Airy-like beam, using an acoustooptics cell. The latter contains a transparent liquid (water), where an ultrasound wave propagating and creating a sinuso
