Numerical Simulation of Eccentric Spatiotemporal Dual-and-Trible Optical Vortices
The spatiotemporal optical vortex has attracted the attention of researchers due to its unique property of carrying transverse orbital angular momentum. Compared with ordinary vortex beams, it can provide additional degrees of freedom and marks a higher level of modulation of light fields. Based on the spatiotemporal-spatial optical vortex with spiral phases in both spatiotemporal and spatial domains, the spatiotemporal-spatiotemporal optical vortex and spatiotemporal-spatiotemporal-spatial optical vortex with spiral phases on two different spatiotemporal planes are numerically simulated. According to the concentric situation between different vortices in the usual spatiotemporal optical vortex, by introducing parameters to modulate the position of the center of the spatiotemporal domain vortex, we have achieved the goal of eccentricity between different vortices and numerically simulated eccentric double vortex and eccentric triple vortex. This research enriches the mode of spatiotemporal optical vortices and provides a theoretical basis for their subsequent research.
