Abstract

Numerical techniques for simulation of electromagnetic wave propagation within fiber amplifiers are discussed. Since a full-featured simulation using the Maxwell system on a realistic fiber is beyond reach, simplified models using Coupled Mode Theory (CMT) form the state of the art. This work presents a novel concept of an equivalent short fiber, namely an artificial fiber which imitates a longer fiber in essential characteristics. A CMT simulation on an equivalent short fiber requires only a fraction of the computational resources needed to simulate the full length fiber.
