Abstract:
1. An optoelectronic semiconductor component comprising: a semiconductor layer sequence having at least one active layer, and a photonic crystal that couples radiation having a peak wavelength out of or into the semiconductor layer sequence, wherein the photonic crystal is at a distance from the active layer and formed by superimposition of at least two lattices having mutually different reciprocal lattice constants normalized to the peak wavelength, wherein the two lattices are hexagonal lattices, wherein the following is satisfied for the two normalized reciprocal lattice constants G 1 and G 2 : where λ 0 is the peak wavelength in a vacuum and A 1 , A 2 are distinct real lattice constants, and wherein the following is satisfied for an absolute value of a difference between the two normalized reciprocal lattice constants: 0.5≦|G 1 −G 2 |≦2.5.
