Abstract

The spatial optical solitons in nonlinear optics have been studied by many scholars in recent years, but the dynamic properties of spatial optical solitons under the boundary conditions of transmission media are rarely studied. This paper has done some research in this direction. In nonlinear thermal media with square cross section, the force and the corresponding torque exerted on the soliton by the boundaries is studied based on Ehrenfest's theory, and the propagation dynamics of the soliton under such force and torque are investigated. It is found that when released off center, the soliton's trajectory pattern will experience a transition from a horizontal one to a diagonal one when the releasing position is away from the 𝑥 axis. It is also found that there exists bouncing phenomenon when the soliton is released from four special positions.
