Abstract

Surface crystallization of LiNbO3 on xK2O·(35-x)Li2O·30Nb2O5·35SiO2 (0≤x≤35) (mol%) glasses was investigated. The c-axis orientation of surface crystallized LiNbO3 was improved when the glass contained 10 mol% K2O. Furthermore, Li ions in the LiNbO3 crystallites were partially replaced by K ions from the glass. Transparent surface crystallized LiNbO3 films on glasses were prepared by controlled heat treatment, which showed optical second harmonic generation. The estimated second-order non-linear optical susceptibilities were d33 = 6.40 pm/V and d31 = d21 = d24 = d15 = 1/3d33 = 2.14 pm/V for a film 1.33 μm in thickness prepared after heating at 620 °C for 3 h, when the c-axis oriented film was described by a space group Cv.
