Abstract
A vertical resonator laser diode has an active layer sequence for generating a laser radiation, an electrical contact layer, and a current aperture formed of a plurality of aperture layers with current passage openings of different sizes. The sizes of the current passage openings of the aperture layers increase in a direction away from the active layer sequence toward the electrical contact layer. A method for producing a vertical resonator laser diode is also provided.
