Patent ID: 7376294

Claim:
An optoelectronic component with a layer structure, the optoelectronic component comprising: at least one irradiation-sensitive structure in the layer structure having a first refractive index that is able to be permanently altered by irradiation comprising a particle radiation to a second refractive index, and at least one non-irradiation sensitive layer being arranged above the irradiation-sensitive structure, wherein the layer structure in which the irradiation-sensitive structure is embedded comprises SiO 2 , SiO 2 -B 2 O 3 or SiO 2- B 2 O 3- P 2 O 5 ; wherein the second refractive index substantially matches a third refractive index of a particular layer in the layer structure and wherein the at least one irradiation-sensitive structure forms part of a vertical coupler such that light couples between the particular layer and the at least one irradiation-sensitive structure.
