Abstract
A ray model for a laser diode is introduced for analysing a laser-diode/multimode-fibre coupling system. The validity is examined from the point of view of a far-field pattern. It is shown that the maximum coupling efficiency is obtained between the paraxial image point and the best focus, and decreases as the curvature of the planoconvex GRIN lens increases.
