Abstract
Abstract Arrangement for coupling a monomode fibre (1) to a semiconductor laser (4). The coupling arrangement consists of a graded-index optical waveguide (2) of defined length (L) spliced to the monomode fibre (1), and of a spherical or aspherical refracting fibre lens (3), which is fused onto the end of the graded-index optical waveguide (2). The coupling arrangement has the advantage that it has a large aperture angle, a low feedback of the first lens surface and only a few reflecting surfaces, and that it requires few adjusting steps. <IMAGE>
