Abstract

An optoelectronic semiconductor chip (10) is specified, comprising a semiconductor layer sequence (20) having at least two active regions (21, 22) arranged one above another, wherein the active regions (21, 22) each have a first semiconductor region (3) of a first conduction type, a second semiconductor region (5) of a second conduction type and a radiation-emitting active layer (4) arranged between the first semiconductor region (3) and the second semiconductor region (5). The optoelectronic semiconductor chip (10) comprises a mirror layer (6), which is arranged at a side of the semiconductor layer sequence (20) facing away from a radiation exit surface (13), and at least two electrical contacts (11, 12) which are arranged at a side of the mirror layer (6) facing away from the radiation exit surface (13). Furthermore, a light source (30) comprising the optoelectronic semiconductor chip (10) is specified.
