Invited talk "Opportunities and challenges of a Swiss SME in European research projects" during the official Launch of the new EU-program Horizon 2020

The FET-Open project COSIT was successfully completed. The final project review was held on the 28th of January 2014 in Zurich. Public Summary

Terahertz Generators and Detectors

Organic crystals polished, coated and mounted for optical applications
Terahertz generators and detectors are produced and optically prepared
at the facilities of Rainbow Photonics in Switzerland.
