摘要：
We study the propagation of optical vortices in a system which consists of a tandem of a multihelical and twisted anisotropic fiber. We show that at certain resonance regimes of the optical fibers such a system allows one to control sign flipping of the topological charge and the circular polarization of the input optical vortex. Moreover, parameters of the multihelical and the twisted anisotropic fibers are established for the implementation of a logical operation that corresponds to the sequential executing of two fundamental SWAP and CNOT gates over the states of circularly polarized optical vortices.
