Abstract

This work intends to present various Photonic Crystal fibers (PCF) for the propagation of orbital angular momentum(OAM) modes. Hexagonal, spiral and octagonal-shaped fibers are designed for the observation of OAM modes. The proposed fiber designs have shown high purity of nearly 90% and has proved that the hexagonal design has the highest mode confinement. The finite element method is employed to obtain 12 OAM modes at the operating wavelength of 1.55 μm.
