Paper Abstract

As a rule, an initial field of the optical vortex at the fiber input transforms into a mode mixture through a short distances due to slight external perturbations so that the field at the fiber output is not suitable for different optical vortex applications in fiber-optical sensors etc. However, as it is shown in the given paper, the tunneling effect that acts between two near by low-mode fibers enables us to select the vortex and other modes into different waveguide canals. The theoretical and experimental results illustrate such the amazing process.
