Polarization properties of the Airy beam
Optics Letters, 2015Polarization of paraxial Airy beam solutions of Maxwell's equations and its evolution with propagation have been studied. We experimentally demonstrate the existence of the cross-polarization component of the Airy beam, typical of nonplanar phase fronts, and study its evolution with propagation.

Virtual source for an Airy beam
Optics Letters, 2012We identify a virtual source for generating an Airy wave. A spectral integral expression is derived to describe the Airy wave, which, in the paraxial limit, yields the freely accelerating, nondiffracting, and finite energy Airy beam. From the spectral representation of the Airy wave, the first two orders of nonparaxial corrections to the paraxial Airy ...

A finite-energy bending Airy beam solution to the paraxial equation in free space was first formulated analytically by Siviloglou and Christodoulides and subsequently demonstrated experimentally by Siviloglou, Broky, Dogariu and Christodoulides. This work was motivated by the infinite-energy (nonspreading) accelerating Airy solution to the Schrudinger ...

We discuss finite-energy and infinite-energy Airy beams of the second kind. Similarly to the well-known paraxial Airy beams, these are accelerating beams that can be analytically described in the Fresnel diffraction zone but propagate along a hyperbolic rather than parabolic path over a certain length, with their “gravity center” shifting linearly with

SPIE Proceedings, 2009
Airy beams are of great interest as a result of their unusual characteristics, they are non-diffracting and also propagate along a parabolic path due to the presence of a transversal acceleration component. In this paper the generation of a white light Airy beam is presented, an investigation is also carried out to determine how the properties of an

Beam propagation factor of an Airy beam
Journal of Optics, 2011We investigate the beam quality features of an Airy beam during propagation in free space. The beam propagation factor of an Airy beam is derived based on the moments method. The results show that the beam propagation factor of an Airy beam can achieve the minimum M2 = 1.17 when the modulation parameter a = 0.756 by compromising the effects of lateral ...

Image signal transmission with Airy beams
Optics Letters, 2015We propose and demonstrate an approach for image signal transmission based on self-accelerating Airy beams. The spatial information is encoded in the Fourier space through a 4-f telescope system, which can circumvent obstacles to realize a self-bending signal transmission.

The ?paraxiality? of some Airy-function-related beams is discussed specifically on the basis of two paraxiality criteria, the paraxiality estimator and the degree of paraxiality, that have been recently introduced in the literature with the intent of assessing the limits of the paraxial approach to light field propagation analysis and of quantifying ...
