A Simplified Model for Linear Mode Coupling in Multimode Fibers with Experimental Assessment

arXiv:2609.20617

Abstract

We propose a novel surrogate model for linear coupling in graded-index multimode fibers that is computationally more efficient than existing models, and can be tuned through a single measurable parameter. The model is benchmarked numerically and experimentally on a 90-polarization-mode fiber.
