ABSTRACT:
To improve the stability and optical transmission properties of an optical waveguide module (1), a fillet-shaped supporting body (12, 13, 13') is used to hold the end (15) of a fiber, particularly of a polarization-maintaining fiber. The top side of the supporting body contains a groove (14) which extends in the direction of the body's longitudinal axis and in which the fiber end (15) is completely sunk and embedded in adhesive. After proper alignment, polished end faces of the fiber and the supporting body (12, 13, 13') are attached to the substrate (2) with adhesive.
