Non-Paraxial Accelerating Beams

open access: yes, 2012
We present the spatially accelerating solutions of the Maxwell equations. Such non-paraxial beams accelerate in a circular trajectory, thus generalizing the concept of Airy beams.

The Gouy phase of Airy beams

open access: yesOptics Letters, 2011
The phase behavior of Airy beams is studied, and their Gouy phase is defined. Analytic expressions for the idealized, infinite-energy type beam are derived. They are shown to be excellent approximations for finite-energy beams generated under typical experimental conditions.

Dynamic Control of Airy Beams Using Real-Time Phase-Amplitude Encoding on a Spatial Light Modulator

open access: yesOptics
Airy beams showing curved paths have found extensive applications in fields such as optical trapping, biomedical analysis, and material processing. Despite their utility, dynamic control of Airy beams poses a significant challenge. This work investigates

Generation of Talbot-like fields

open access: yesScientific Reports, 2021
We present an integral of diffraction based on particular eigenfunctions of the Laplacian in two dimensions. We show how to propagate some fields, in particular a Bessel field, a superposition of Airy beams, both over the square root of the radial ...

Plasmonic Metalens to Generate an Airy Beam

open access: yesNanomaterials, 2023
Airy beams represent an important type of non-diffracting beams—they are the only non-diffracting wave in one dimension, and thus they can be produced with a cylindrical geometry that modifies a wavefront in one dimension.

On the dynamics of Airy beams in nonlinear media with nonlinear losses

open access: yes, 2015
We investigate on the nonlinear dynamics of Airy beams in a regime where nonlinear losses due to multi-photon absorption are significant. We identify the nonlinear Airy beam (NAB) that preserves the amplitude of the inward H\"ankel component as an ...

Decelerating Airy pulse propagation in highly non-instantaneous cubic media [PDF]

open access: yes, 2017
The propagation of decelerating Airy pulses in non-instantaneous cubic medium is investigated both theoretically and numerically. In a Debye model, at variance with the case of accelerating Airy and Gaussian pulses, a decelerating Airy pulse evolves into

Three-Airy Beams, Their Propagation in the Fresnel Zone, the Autofocusing Plane Location, as Well as Generalizing Beams

open access: yesPhotonics
A family of 2D light fields consisting of the product of three Airy functions with linear arguments has been studied theoretically and experimentally.

Design, transform and control of optical field in discrete optical system: an example

open access: yesScientific Reports, 2017
A discrete optical system can broaden the spatial distribution of the input light through optical coupling in array waveguides, just like diffraction in continuous media.

Propagation-invariant vortex Airy beam whose singular point follows its main lobe

open access: yesNew Journal of Physics, 2021
We propose and demonstrate a novel vortex Airy beam which is a superposition of an Airy beam and its laterally sheared beam with a π /2 phase shift.
