The main focus of the research in this laboratory is the development of new devices and application in the infrared region of the spectrum. A specific focus is thereby on security as well as communication application.
In a long term study the laboratory compares since 2001 atmospheric propagation at different wavelengths in indoor and outdoor studies to find the optimal wavelength for free-space optical communication. It uses a quantum cascade laser to transmit data using the mid-infrared part of the spectrum, which propagates much more favorably under bad weather conditions like fog.
A secondary focus of research is based on the component development for the far-infrared spectral region, the so-called terahertz spectrum. Components include modulators and lenses, and are based on optical excitation which allow for active control.
