Method and device for establishing an optical connection between an optoelectronic component and an optical waveguide

Abstract

A method for establishing an optical connection between at least one optoelectronic component arranged in a first substrate and emitting or receiving optical radiation substantially perpendicular to a substrate surface of the first substrate, and at least one optical waveguide aligned with a first end substantially parallel to the substrate surface. The method comprises providing a second substrate that is transparent for at least one wavelength range of the optical radiation, and applying a layer of material on the second substrate. The layer is transparent, at least after structuring, for the wavelength range. The method also comprises structuring the layer of material in such a manner that the structured material forms both a lateral guide for the first end of the optical waveguide and an optical deflection element establishing an optical connection through the second substrate between the optoelectronic component and the first end of the optical waveguide, and joining the second substrate to the first substrate.
