Modeling of Fiber for Orbital Angular Momentum Modes Propagation

Abstract

The use of OAM (Orbital Angular Momentum) states of light for multiplexing the channels in communication systems has become of great interest, both for free space telecommunications, and those using fiber optics. The ever-increasing need for digital data transfer is driving the development of new technologies to increase network capacity, especially with regard to fiber optic networks. The present study made it possible to model an ACF fiber (Air-Core Fiber) accepting OAM modes with the aim of transmitting information on these modes. This consists of considerably increasing the number of channels and therefore increasing the optical transmission capacity. Thus we have proposed an air core ring fiber (ACF) model with the ability to transmit OAM beams.
