Abstract: Mode coupling, caused by random variations of core index or random irregularities of the fiber wall, influences the transmission characteristics of multimode optical fibers in a complicated way. The
In this paper, we present a new and more realistic theoretical framework for lightwave propagation in a multimode graded index (GRIN) optical fiber when the fundamental mode is selectively excited into
