ABSTRACT:
In the manufacture of laser diodes having a stripe-shaped, active layer, a problem arises upon application of lateral layers, particularly of blocking pn-junctions for lateral current conduction, in that these layers are undesired above the active layer. By applying a protective cover layer that will dissolve in super-cooled melts of the material of the lateral layers, before the growth of the lateral layers, the growth of the lateral layers, particularly blocking pn-junctions, above the active stripe is avoided since the cover layer dissolves in the melt given epitaxial application of the lateral layers.
