ELECTRO-OPTIC EFFECTS OF La-MODIFIED PMN-PT THIN FILMS FOR WAVEGUIDE APPLICATIONS
Abstract:Lanthanum-modified lead magnesium niobate titanate (PLMNT) thin films were fabricated on glass, silicon and sapphire substrates successfully via a chemical solution deposition process. The PLMNT thin films exhibited large electro-optic (EO) coefficients with La concentrations between 2.0-2.5 mol%. The largest EO coefficient was measured in a PLMNT thin film about 1 m thick deposited on r-cut sapphire substrate. The effective EO coefficient r31 measured at 532 nm was as large as 1079 pm/V.
