TL;DR: In this article, two dimensional Airy beams were generated using a cubic phase mask and its propagation through photorefractive material was studied experimentally. And the effect of an applied electric field on the propagation of Airy beam through photoresistive materials numerically was also studied.
Abstract: We generate two dimensional Airy beams using a cubic phase mask and study its propagation through photorefractive
material experimentally. The diffraction free nature as well as the acceleration of Airy beams is observed. Using beam
propagation method (BPM), we confirm the experimental results. We also study the effect of an applied electric field on
the propagation of Airy beams through photorefractive materials numerically. It is observed that the applied field leads to
interaction between the lobes of Airy beams.
