Abstract
A vertical resonator laser diode and a method for fabricating it are described. Electrical connecting contacts can be disposed on a common main surface of the laser diode, for example its light exit side. For this purpose, in the course of the fabrication method, a contact-making zone is produced by indiffusion of impurity atoms, by which zone that side of the pn junction which is remote from the main surface can be electrically conductively connected to the main surface and be provided with a corresponding connecting contact.
