Parabolic nondiffracting optical wave fields
TLDR
The existence of parabolic beams that constitute the last member of the family of fundamental nondiffracting wave fields and their associated angular spectrum is demonstrated and their eigenvalue spectrum is continuous.Abstract:
We demonstrate the existence of parabolic beams that constitute the last member of the family of fundamental nondiffracting wave fields and determine their associated angular spectrum. Their transverse structure is described by parabolic cylinder functions, and contrary to Bessel or Mathieu beams their eigenvalue spectrum is continuous. Any nondiffracting beam can be constructed as a superposition of parabolic beams, since they form a complete orthogonal set of solutions of the Helmholtz equation. A novel class of traveling parabolic waves is also introduced for the first time.read more

Transmission characteristics of subpicosecond Airy pulses in silicon-on-insulator waveguides
TL;DR: In this paper, the authors numerically simulated the propagation evolution of a sub-picosecond Airy pulse in silicon-on-insulator waveguides and found that under the combined action of group velocity dispersion and third-order dispersion (TOD), the airy pulse undergoes inversion.

Spinning parabolic cylindrical beams in free space
D. M. Deng,Qi Guo +1 more
TL;DR: In this paper, a class of paraxial beams which are named spinning parabolic cylindrical beams (SPCBs) are introduced in free space, and the transverse position of the vortex can be controlled by varying the distribution factor.

Propagation-invariant vortex Airy beam whose singular point follows its main lobe
TL;DR: In this paper, the authors proposed a vortex Airy beam which combines the characteristics of an optical vortex and a diffraction-free airy beam, which exhibits stable propagation dynamics, wherein its singular point closely follows its main lobe, unlike conventional vortex airy beams.

Vortex Modulation of a Linearly Polarized Lorentz- Gauss Airy Beam
TL;DR: In this article, focusing characteristics of the linearly polarized Lorentz-Gauss vortex Airy beam were studied with other parameters unchanged, as the number of topological charges increases, the focal spot map will split regularly, gradually splitting from the center into two symmetrical points.

A Course of Modern Analysis
TL;DR: The volume now gives a somewhat exhaustive account of the various ramifications of the subject, which are set out in an attractive manner and should become indispensable, not only as a textbook for advanced students, but as a work of reference to those whose aim is to extend the knowledge of analysis.

Exact solutions for nondiffracting beams. I. The scalar theory
TL;DR: In this paper, exact nonsingular solutions of the scalar-wave equation for beams that are non-diffracting were presented, which means that the intensity pattern in a transverse plane is unaltered by propagating in free space.
