Abstract
It has been shown numerically that coupled nonlinear Schrödinger equations describing the interaction between the left and right circular polarizations of a paraxial optical wave in a defocusing Kerr medium with an anomalous dispersion in a helical waveguide have stable solutions in the form of elongated stationary rotating bubbles with several optical vortices attached to the ends. A bubble is an arbitrarily long quasi-cylindrical three-dimensional cavity in one of the components filled with the opposite component. The transverse profile of the bubble is determined by the shape of the cross section of the waveguide, the helix pitch, the number of vortices, and the background intensity of the surrounding component rather than by the total amount of the filling component.
