  • Abstract
    A new diffusion technique for the reliable fabrication of low loss Ti:LiNbO3 waveguides is reported. During diffusion, the LiNbO3 sample is placed in a closed platinum crucible where the sample itself serves as an Li2O source to eliminate the appearance of unwanted surface waveguides. The influence of the diffusion conditions (temperature, addition of water vapour) on the waveguide performance is discussed.
