Superoscillations in Finite-Energy Airy Beams
Superoscillations naturally arise in optical fields with dense packing of nodal points of amplitude. Airy wave packets are highly oscillatory and rich of phase singularities. We study to the best of our knowledge, for the first time, the superoscillatory

We report on the numerical simulation results of the propagation of Fourier-transformed super-Gaussian beams with cubic phase modulation, which we refer to as super-Airy beams. We show the effect of the truncation profile on the propagation of the "Airy" intensity distribution and propose methods to improve the non-diffracting propagation length.

We derive a general form of Airy wave function which satisfies paraxial equation of diffraction. Based on this, we propose a new form of Airy beam, which is composed of two symmetrical Airy beams which accelerate mutually in the opposite directions. This 'dual' Airy beam shows several distinguishing features: it has a symmetric transverse intensity ...

Generation of electron Airy beams [PDF]
Within the framework of quantum mechanics, a unique particle wave packet exists in the form of the Airy function. Its counterintuitive properties are revealed as it propagates in time or space: the quantum probability wave packet preserves its shape despite dispersion or diffraction and propagates along a parabolic caustic trajectory, even though no ...

The Airy beams are analyzed in order to provide a cogent physical explanation to their intriguing features which include weak diffraction, curved propagation trajectories in free-space, and self healing. The asymptotically exact analysis utilizes the method of uniform geometrical optics (UGO), and it is also verified via a uniform asymptotic evaluation

Transverse Spin Angular Momentum of Airy Beams
We show that a (1+1)D Airy beam can contain the density of spin angular momentum (SAM) normal to the direction of propagation if the polarization direction of its magnetic-field component is orthogonal to the transverse axis of the Airy profile. Although

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