Owing to the unique features in intensity and phase structures, optical vortex lattices (OVLs)
have attracted intensive attention and promoted various applications. However, the power …

As an essential component of the vortex beam, the fractional vortex beam has significantly
advanced various applications, such as optical imaging, optical communication, and particle …

Laguerre–Gaussian (LG) beams have orbital angular momentum (OAM). A particle trapped
in an LG beam will rotate about the beam axis, due to the transfer of OAM. The rotation of the …

The customization of optical vortices with controllable structures is of fundamental
importance for promoting various applications such as materials processing, optical …

The high-power mode-programmable orbital angular momentum (OAM) beam has attracted
significant attention in a wide range of applications, such as long-distance optical …

The existence, stability and propagation of spatial solitons in double-well potentials with
cubic nonlinearity are investigated. The symmetric, tripole and quadrupole solitons show …

We investigate the dynamics of two component bright-bright (BB) solitons through
reflectionless double barrier and double well potentials in the framework of a Manakov …

Alongside the well-known solutions of standard beams, elegant Gaussian beams (eGBs)
have been presented as alternative solutions to the paraxial wave equation. In this work, we …

A method based on the distribution theory is introduced to compute the Fresnel diffraction
integral. It is applied to the diffraction of Gaussian and Laguerre–Gauss beams by a circular …

The higher capability of optical vortex beams of penetrating turbid media (eg, biological
fluids) with respect to the conventional Gaussian beams is, for the first time to our …
