Coupled nonlinear Schrodinger equations for paraxial optics with two circularpolarizations of light in a defocusing Kerr medium with anomalous dispersioncoincide in form with the Gross-Pitaevskii equations for a binary Bose-Einsteincondensate (BEC) of cold atoms in the phase separation regime. In this case,the helical symmetry of an optical waveguide corresponds to rotation of thetransverse potential confining the BEC. The "centrifugal force" considerablyaffects the propagation of a light wave in such a system. Numerical experimentsfor a waveguide with an elliptical cross sections have revealed characteristicstructures consisting of quantized vortices and domain walls between twopolarizations, which have not been observed earlier in optics.
