OAM Modes in Fiber

OAM Modes in Fiber : Optical fibers support different types of modes depending on their refractive index profile. In step-index fibers, the fundamental modes are linearly polarized (LP), but in ring-core fibers (RCFs), the natural modes are hybrid modes, specifically HE (hybrid electric) and EH (hybrid magnetic) modes. These modes arise due to the vector […]
