Abstract:
1. A method for producing a laser diode arrangement, comprising: providing a semiconductor substrate; epitaxially growing a first single light source, comprising a first laser stack having an active zone, a first n-contact layer and a first p-contact layer; depositing a first dielectric layer on a partial region of the first p-contact layer; epitaxially growing an intermediate layer on the first p-contact layer; epitaxially growing at least one second single light source, comprising a second laser stack having an active zone, a second n-contact layer and a second p-contact layer; depositing a second dielectric layer on a partial region of the second p-contact layer; removing the at least two dielectric layers by means of etching or lift-off in order to expose contact surfaces; depositing contacts on the exposed contact surfaces and on the exposed contact layer furthest away from the substrate.
