Notes:
The ferroelectric (Pb,La)(Zr,Ti)O3 optical waveguiding thin films have been prepared on MgO coated (100)LiF substrates by pulsed laser deposition. X-ray θ-2θ scans revealed that the films are single-phase pseudocubic perovskite and highly 〈100〉 textured. The surface chemical composition of the as-grown films was determined by x-ray photoelectron spectroscopy. The ferroelectric properties of the films as grown on Pt/Ti coated silicon were demonstrated by using a modified Sawyer–Tower circuit, and the optical waveguiding properties of the films were characterized by using a rutile prism coupling method. The as-grown films have an average transmittance of 75% in the wavelength range of 400–2000 nm and a refractive index of 2.2 at 632.8 nm close to the bulk PLZT. The distinct m lines of the guided TM and TE modes of the films as grown on MgO coated LiF substrates have been observed. © 1995 American Institute of Physics.
