Abstract
We present a theoretical and experimental study on the propagation and polarization control of hybrid-order Poincaré beams—composed of two vortex beams with different orders—in nonlocal, nonlinear lead glass. The linear stability analysis reveals that stable solitons form only when the power and width of the component vortices satisfy certain conditions. Furthermore, we numerically establish that the polarization rotation of these beams can be controlled linearly by varying the power, and we analytically demonstrate that such a phenomenon arises from different phase shifts between the component beams. The theoretical predictions agree well with the experimental results. This suggests that the controllable polarization evolution of solitons could open an avenue for optical manipulation, imaging, communications, and other photonic applications.
