Abstract
A light emitting diode with a stacked structure, having a first region and a second region, wherein both regions comprise the following layers in the stated order, a carrier layer and an n-doped lower cladding layer and an electromagnetic radiation-generating active layer. The active layer comprises a quantum well structure and a p-doped upper cladding layer, and the first region additionally comprises a tunnel diode formed on the upper cladding layer from a p-layer and an n-layer, and an n-doped current distribution layer, wherein the current distribution layer and the n-doped contact layer are covered with a conductor track layer structure. At least the lower cladding layer, the active layer, the upper cladding layer, the tunnel diode and the current distribution layer are monolithic. The second region has a contact hole with a bottom region, an injection barrier being formed in the bottom region of the contact hole.
