A light fiber winding around a curved path model can generate a large vortex Bessel solitary wave (BSW). The spiral body structure BSW can carry orbital angular momentum (OAM) modes. We investigate the influence of curved path and the type of winding of the principal ray based on the OAM modes. The curve path corresponds to the intensity of the modes of the OAM beam. Our vortex BSW is different from traditional electromagnetic amplitude solitary waves. We calculate the propagating diffraction pattern in the optical fibers, and find that a fundamental BSW is an Airy spot. Along with increasing the order number, we also see that the vortex BSW decays gradually from the center to the exterior, and the BSW leaks more energy to the outer rings. |
