Abstract
Linear electro-optic modulation of a guided light beam has been observed in an unpoled thin film of Pb(Zr0.53 Ti0.47)O3 prepared by the sol-gel method on a [100] SrTiO3 substrate. For the TE1 mode of a two-mode waveguide, an effective Pockels coefficient of ∼ 50 pm/V, at a wavelength of 633 nm, was determined by the method of diffraction by an induced electro-optic Bragg grating.Keywords
