Research Interests:

The Optical Materials Group is involved in the development of new optical materials for applications in the areas of lasers, waveguide devices and biosensors.  Materials being studied include rare-earth and transition-metal doped glasses and glass-ceramics for waveguide devices, porous glass-ceramics for biomedical applications, and (in collaboration with the Materials Science and Applications Group) transition metal doped II-VI semiconductor crystals which are promising materials for near-infrared laser applications.
