A fast, accurate and simple field coupling model is presented which is capable of describing mode coupling effects due to bends and splices in multimode fibers with parabolic index profile as well as the coupling losses induced by this process. This model is validated numerically by comparing the results to the well-known coupled amplitude theory model yielding the same relative bandwidth increase...
Multimode fibers (MMF) have attracted much attention recently because of its potential of increasing the transmission capacity by the number of guided modes. Because of this, it is necessary to develop fast and simple methods to estimate transmission effects like mode coupling along the MMF and the losses induced by it. Mode coupling theory [1] provides a possibility for describing amplitude and phase...
