TL;DR

This paper explores how multiple beams can propagate simultaneously in an Anderson localized optical fiber, demonstrating potential for high-density channel use and practical beam-multiplexing despite fiber bends.

Contribution

It introduces the concept of multiple-beam propagation in Anderson localized fibers and analyzes the impact of macro-bending on beam stability for practical applications.

Findings

Multiple beams can coexist with exponential profile decay.

Fiber bends induce beam drift but can be managed.

Potential for practical beam-multiplexing applications.

Abstract

We investigate the simultaneous propagation of multiple beams in a disordered Anderson localized optical fiber. The profiles of each beam fall off exponentially, enabling multiple channels at high-density. We examine the influence of fiber bends on the movement of the beam positions, which we refer to as drift. We investigate the extent of the drift of localized beams induced by macro-bending and show that it is possible to design Anderson localized optical fibers that can be used for practical beam-multiplexing applications.
