Abstract
Abstract Surface-light-emitting diode in which a first contact (5) is deposited as a layer on a surface extending parallel to the plane of an active layer (3) provided for producing radiation and sufficiently close to said active layer (3), and said surface is structured in a grating-like manner in such a way that, when the device is being operated, polar surface-plasma ions are excited on the free surface of the first contact (5); these ions produce a strongly directed radiation. <IMAGE>
