An Investigation of PLZT for Integrated Optics.
Abstract
Lanthanum modified lead zirconate-lead titanate ceramics (PLZT) possesses many unique electrooptic and optical properties. Its utilization for integrated optic applications were investigated. Significant research results obtained from this investigation are: Graded refractive index was achieved in PLZT by polishing, by diffusion and by electrooptic techniques. Optical waveguiding was achieved in optically polished PLZT wafers; An integrated optic waveguide modulator was constructed, utilizing the electric field induced scattering effect for beam intensity modulation. The modulation efficiency was 30mW/MHz for 50% modulation index; Single crystals of PLZT films up to 500 micrometers in size were obtained and major parameters governing the epitaxial growth were identified; and Large refractive index change of PLZT ceramics from 2.5 to 1.6 were achieved by out-diffusion.
