Abstract
A simple and useful calculation method for obtaining an InGaAsP laser-diode/multimode-fibre coupling characteristic is presented. The attenuation effects of higher-order modes in the multimode fibre are introduced into the ray tracing. Agreement between theoretical and experimental coupling characteristics is greatly improved in comparison to that for the conventional ray tracing.
