WebApr 10, 2024 · Airy beams are an intriguing type of non-diffraction wave packet that can exist in one-dimensional (1D) curved orbital plane systems. These beams have gained significant attention due to their unique properties, including non-diffraction, self-healing, and self-bending. In this study, we propose a method for generating high-efficiency and … WebFeb 15, 2024 · The propagation properties of OVs embedded in a circular Airy beam were extensively studied [18]. Meanwhile, the propagation of OVs carried by radially polarized circular Airy beams has been investigated [19]. Recently, Pearcey beams were theoretically introduced and experimentally generated in 2012 [20].
The term "Airy beam" derives from the Airy integral, developed in the 1830s by Sir George Biddell Airy to explain optical caustics such as those appearing in a rainbow. The Airy waveform was first theorized in 1979 by M. V. Berry and Nándor L. Balázs. They demonstrated a nonspreading Airy wave packet solution to the Schrödinger equation. In 2007 researchers from the University of Central Florida (United States) were able to create an… WebMar 10, 2024 · Ring-Airy beams have attracted increasing interest owing to its unusual ability to abruptly autofocus toward the focal point along a parabolic trajectory.
