  • Title: Stabilization and breakup of optical vortices in presence of hybrid nonlinearity.
    Author: Gan X, Zhang P, Liu S, Zheng Y, Zhao J, Chen Z.
    Journal: Opt Express; 2009 Dec 07; 17(25):23130-6. PubMed ID: 20052240.
    Abstract:
    We study nonlinear propagation of optical vortices in presence of hybrid nonlinearity as established in a nonconventional biased photorefractive crystal. Our results indicate that under hybrid nonlinearity the breakup of a singly-charged vortex along with the loss of its angular momentum is suppressed considerably as compared with that under conventional self-focusing or self-defocusing nonlinearity. Disintegration of a doubly-charged vortex under hybrid nonlinearity is also presented. Our experimental results are in good agreement with the numerical simulations.
