Materials doped with rare-earth are of crucial importance in optoelectronics and are widely deployed in fiber amplifiers and solid-state lasers. Intense efforts are on-going worldwide to develop new fiber with better laser/amplifier performances of the fibers. These new fibers should exhibit a minimum increase of transmission losses during lasing.
In this project, new optically active glasses and glass-ceramics will be developed and drawn into fibers. The main goal is to understand the effect of the glass/glass-ceramic network on the RE luminescence properties and the material photo-response during lasing in order to engineer new fibers. The originality of the project lies in the development of fibers drawn from glass-ceramics and nanoparticles-containing glasses. The proposed effort is interdisciplinary and will require know-how in glass science, optical and luminescence properties, nucleation and growth, glass-light interaction and fiber drawing and characterization.
