Radiation-emitting chip

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 p...

Summary: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 ).
