Circular Airy Beam Based on Bandpass Filter [PDF]

open access: goldIEEE Photonics Journal, 2020
A new type of circular Airy beams is demonstrated by using a bandpass filter, in order to enhance the field intensity at the focal point of light beam, based on the angular spectrum representation and the ray optics picture. The specific ring and the key

Experimental investigation in Airy transform of Gaussian beams with optical vortex

open access: yesResults in Physics, 2021
The Airy transform was first introduced for a Gaussian beam, and the output beam is an Airy beam. When the Gaussian beam is extended to the Gaussian beam with optical vortex, what kind of output beam will be achieved by executing the Airy transformation.

Accelerating Airy Beams Along Tunable Propagation Trajectories

open access: yesIEEE Photonics Journal, 2017
We present a simple and highly efficient approach to directly generate tunable Airy beams, which can propagate along arbitrary monotonic curves. Such beams are generated by modulating a Gaussian beam imposed by tunable phase-only patterns.

Wideband Airy Beam Generation Using Reflective Metasurfaces with Both Phase and Amplitude Modulation

open access: yesPhotonics, 2023
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 ...
