Optical Field Rotation of Finite Energy Airy-Hermite-Gaussian Beams in Medium with Potential Well

Herein, for the propagation and interaction of finite energy Airy-Hermite-Gaussian (FEAHG) beams in a medium with a potential well, a linear parabolic (Schrodinger-like) equation was applied as the theoretical model in a split-step Fourier numerical simulation. Results show that the optical field structure of FEAHG beams rotates in the medium with a potential well. The greater the intensity or the potential well is, the shorter the propagation distance for the optical field structure completing rotation is. In addition, further investigation of the interaction between two FEAHG beams with different initial intervals in the medium with a potential well reveals that the number of light spots during propagation changes.
