Abstract :
The aim of this paper is to obtain an analytical expression for intrinsic coupling losses in multistep index (MSI) fibers. For this purpose, a uniform power distribution is assumed. In order to validate the theoretical expression, the obtained results were compared with computer simulations using the ray-tracing method as well as with results obtained using existing models for step index (SI) and clad power-law profile graded index (GI) fibers. This analytical expression will provide fiber manufacturers with a very valuable tool for the assessment of fiber quality in terms of waveguide tolerances
