Development of Praseodymium doped fluoride waveguide
Résumé
We report on the study of praseodymium doped ZBLA channel waveguides obtained by ionic exchange. Fluorozirconate glasses synthesis, photolithography process and ionic exchange are studied. Chemical characterizations are performed on waveguides, as well as refractive index profile. Spectroscopic measurement and emission cross section calculation are also reported. These results show the ability of rare earth doped fluoride glasses channel waveguide to serve as active materials for integrated solid state laser sources.
