Materials for Photonic Applications

Light as carrier of information and energy is of special interest in laser glass technology, telecommunication, optoelectronic and multimedia industry. The avai-liability of suitable materials for photonic applications and the meeting of the demands for these materials are essential for the technological progress.

At present, the studies are focused on following problems:

• development of Yb fluoride-phosphate laser glass
• optimization of Yb doped glasses for ultrashort femtosecond pulses
• multicomponent upconversion glass
• stabilization of fibers of commercial laser glasses due to application of special fusion techniques
• glass for eye safe region laser application

For these purposes, special fluoride based glasses have to be developed concerning its composition (several glass forming systems with variable values of several dopants), structure (local structure), and properties (optimized absorption, emission, high quantum yield, slope efficiency).

Further work is focused on preparation of inexpensive thin solid films as potential functional layers (light emission, photovoltaic and sensoric applications).
