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