EDGE-EMITTING SEMICONDUCTOR LASER CHIP HAVING A STRUCTURED CONTACT STRIP

摘要

The invention specifies an edge-emitting semiconductor laser chip having - an active zone (14) in which electromagnetic radiation is produced during operation of the semiconductor laser chip (1) and - at least one structured contact strip (2) which is structured in such a manner that charge carrier injection into the active zone (14) decreases towards a side of the semiconductor laser chip (1) on which a coupling-out facet (3) of the semiconductor laser chip (1) is situated.
