Abstract

The invention relates to a radiation-emitting semiconductor chip (1) that emits polarized light using the Purcell effect. Such a semiconductor (1) emitting polarized radiation comprises a radiation-generating active zone (3) and a polarizing filter (5). The radiation-generating active zone (3) is arranged between a radiation-extracting surface of the semiconductor chip (1) and the polarizing filter (5).
