Abstract:
1. An optoelectronic device having an active layer comprising a multiplicity of structural elements laterally spaced apart from one another, wherein the structural elements each have a quantum well structure comprising at least one barrier layer composed of In x1 Al y1 Ga 1-x1-y1 N, wherein 0≦x1≦1, 0≦y1≦1 and x1+y1≦1, a plurality of intermediate layers composed of In x Al 1-x N, wherein 0≦x≦0.6, and at least one quantum well layer composed of In x2 Al y2 Ga 1-x2-y2 N, wherein 0≦x2≦1, 0≦y2≦1 and x2+y2≦1, wherein the quantum well structure is a multiple quantum well structure in which the barrier layer and the quantum well layer are repeated a number of times with a first period length and the intermediate layers are repeated a number of times with a second period length, the first period length not being the same as the second period length.
