Elliptically polarized spatial solitons in cubic gyrotropic materials

The problem of soliton propagation in nonlinear Kerr medium with Linear optical activity and cubic anisotropy is considered. It is shown that balance between the nonlinearity and linear gyrotropy results in the existence of spatial elliptically polarized solitons with fixed state of polarization, For these novel stationary solitons, the bifurcation diagrams are constructed and preliminary stability analysis is carried out. The evolution of the state of polarization of the solitons nearby the stationary states is described using the Stokes parameters.
