Propagation dynamics of hybrid-order Poincare beams in thermal nonlocal media

We study the propagation dynamics of hybrid-order Poincare (HOP) beams, consisting of two coaxially propagating, orthogonal circularly polarized beams with different topological charges, in a nonlocal medium with thermal nonlinearity. By numerically observing the evolution of beamwidth, isosurface and light intensity with propagation distance, we verify that a HOP soliton with a certain beamwidth ratio can exist only at a proper power ratio. At a fixed propagation distance, the rotation of polarization component of the HOP breather can be controlled linearly by the input power. The polarization of HOP beams is observed as a function of the propagation distance, and the evolution regularity of the polarized rotation angle and ellipticity angle of HOP soliton and HOP breather is summarized.

We study the propagation dynamics of hybrid-order Poincare (HOP) beams in a nonlocal medium with thermal nonlinearity. The existence of a HOP soliton with a certain beamwidth ratio is verified under proper power ratio. The rotation of polarization component of the HOP breather can be controlled linearly by the input power at a fixed propagation distance. The evolution regularity of the polarized rotation angle and ellipticity angle of HOP soliton and HOP breather is summarized.
