Abstract (en)

[origin: WO03061026A1] An organic layer (1) is applied to a transparent carrier (2) in such a way that several partial segments with different refractive indices are configured in the layer. Fewer photons remain trapped in the layer as a result of waveguide losses than in homogenous layers due to diversion at the phase limits within the layer.
