The aim of the project is in the research into the fabrication and characterization of laser-active optical waveguides suitable for amplification or generation of optical radiation in the near-infrared region. Two basic kinds of active waveguides will beinvestigated, namely the ion-exchanged waveguides in special glasses doped with rare-earth ions like Nd3+ and Er3+ either in the bulk material or by selective doping from the surface, and waveguides formed in the LiNbO3 single crystal by titanium diffusion or proton exchange, co-doped with rare-earth ions by selective doping. “Classical” diffusion doping as well as doping based on ion exchange will be used. Research team of specialists from both the University and the Academy of Science has been created to cover the problems of technology, chemical and structural analysis, optical waveguide design and characterization, laser physics, and diagnostics of physical properties of the active waveguides. It is expected that the active waveguides will find i
