Abstract:
A method of producing a plurality of laser diodes includes providing a plurality of laser bars in a compound, wherein the laser bars each include a plurality of laser diode elements arranged side by side, the laser diode elements each have a common substrate and a semiconductor layer sequence arranged on the substrate, and a splitting of the compound at a longitudinal separation line running between two adjacent laser bars in each case leads to formation of laser facets of the laser diodes to be produced, and structuring the compound at at least one longitudinal separation line, wherein a strained compensation layer is applied to the semiconductor layer sequence at least at the longitudinal separation line or the semiconductor layer sequence is at least partially removed.
