ABSTRACT:
A light-emitting chip (3) has a lens-type coupling-out window (4), whose base area (5) is provided with a mirror area (6). Arranged on a coupling-out area (7) of the coupling-out window (4) is a layer sequence (9), with a photon-emitting pn junction (10). The photons emitted by the pn junction are reflected at the mirror area (6) and can leave the coupling-out window (4) through the coupling-out area (7).
