A surface emitting semiconductor laser chip contains a semiconductor body, which has, at least partly, a crystal structure with principal crystal directions, a radiation exit face, and side faces laterally delimiting the semiconductor body. At least one of the side faces is disposed obliquely with respect to the principal crystal directions.

Surface emitting semiconductor laser chip and method for producing the chip

A light-emitting diode () has a lens body () that is fabricated from an inorganic solid. Fastened on the lens body () are semiconductor chips () that emit light beams (). Furthermore, the light-emitting diode () is provided with a housing () that can be screwed into a conventional lamp holder via a thread ().

Light-emitting diode and method for the production thereof

A light-emitting chip () has a lens-type coupling-out window (), whose base area () is provided with a mirror area (). Arranged on a coupling-out area () of the coupling-out window () is a layer sequence (), with a photon-emitting pn junction (). The photons emitted by the pn junction are reflected at the mirror area () and can leave the coupling-out window () through the coupling-out area ().

Radiation-emitting chip

Proposed for high-performance light-emitting diodes are semiconductor chips () whose longitudinal sides are substantially longer than their transverse sides. Light extraction can be substantially improved in this manner.
