Optoelectronic Device

14048/TUB: Optoelectronic Device


Transforming optical signals into electrical signals or vice versa is of great importance in high speed data transfer to guarantee a fast but also safe signal transfer. So on the one hand it is important to generate a stable electrical contact that is suitable for high-frequency. On the other hand, it is essential to guide the light precisely within the micro meter scale. Current systems use fo example optical lenses for coupling the light. Even though this method is very efficient, it is also a very sensitive one. Therefore it is necessary to adjust those systems very precisely, a fact that enhances the difficulty of handling and processing such devices.

Technical Description

It is thus an object of the invention to provide an optoelectronic device which allows connecting an optoelectronic component of the optoelectronic device to external components in an efficient, reliable and simple way. Therefore, the optoelectronic device comprises an optoelectronic component, a waveguide with an optical waveguide section and an electrical conductor section. The optical waveguide section is transparent for radiation of a given wavelength or a given wavelength range, and capable of guiding the radiation along the longitudinal axis of the waveguide. A major advantage of the device is its one step mechanically butt-coupling: That means, that the optical connection and the electrical connection can be performed in one step.
