Propagation dynamics of optical vortices with anisotropic phase profiles, where the slope of the helical wave front is not uniform in the azimuthal direction, is studied in the linear and nonlinear regimes. Numerical results show that the rotation rate of optical vortices is proportional to the anisotropy and is in good agreement with the analytical approach.
