Abstract
A method for making a set of surface-emitting laser diodes comprises the making of reflectors by the epitaxial growth of at least one semiconductor material through a mask having apertures with inclined flanks. This method leads to the obtaining of the Bragg reflectors obtained in situ, removing the need for the ion etching of a semiconductor substrate followed by a phase for the conditioning of the surface of the sample before the preparation of the desired laser structure. Application: optical power source.
