Notes:
We show SiO2 cladding effects on the optical properties of annealed proton-exchanged LiNbO3 waveguides as well as on the kinetics of annealing process. Annealing with previously deposited SiO2 film reduces the optical losses in annealed proton-exchanged LiNbO3 waveguides. The structural phase diagram of HxLi1−xNbO3 is also modified if annealing has been performed with a previously deposited SiO2 layer. The physical mechanisms, including evaporation of H2O and/or Li2O during annealing without deposited film and, as a result, formation of defects and a lithium deficit phase, are discussed. © 2000 American Institute of Physics.
