Pulsed laser deposition of optical waveguiding strontium barium niobate films

Strontium barium niobate waveguiding thin films were prepared by pulsed laser deposition. The relationship between the him structure and the deposition temperature were analyzed by x-ray diffraction and atomic force microscopy. Waveguiding properties such as refractive index and mode dispersion were examined and a dispersion relation was obtained for the (001)-oriented films. (C) 1997 American Institute of Physics
