Abstract

We investigate the coupling behavior of orbital angular momentum (OAM) modes in ring-core shaped fiber waveguides subject to helical bending. Using both analytical and numerical methods we analyze the effects of the bending radius, frequency and helicity on coupling between modes with different OAM. It is shown that such a system exhibits an asymmetric behavior with respect to the propagation direction. These results can be useful for the design and optimization of OAM-based devices.
