In this work two coupling methods is presented. The attention was focused on the direct butt coupling. The preparation of measurements tool is also depicted with its peculiar details. The investigated coupling efficiency in the dependence on lateral and axial displacement determinates the mutual position of the laser and the waveguide. The results of those measurements are a promising base for further studies and implementation of “waveguide-in-copper” technology in practice.
The examination of angular offset influence on coupling loss are presently under go. Also an detailed characterization of laser beam will be inspected.
ACKNOWLEDGEMENT
This work results from a long lasting cooperation between Wroclaw University of Technology (Poland) and Dresden University of Technology (Germany.) The “waveguide-in-copper” technology was developed in collaboration with Frauenhofer-Institute for Reliability and Micro-Integration (FhG IZM).
