20 November 1996 Neodymium-doped fluoride waveguides development using anionic exchange
Author Affiliations +
The successful fabrication of channel waveguide in rare earth doped fluoride glass substrates is reported. A new process using anionic exchange between F- ions of the substrate and OD- ions of D2O vapor was developed. The guiding configuration has been qualified by m-liens method and near filed measurement, and the active properties of the channel waveguides are presented.
