摘要：

The magnitudes of linear electrooptic coefficients r13 and r33 in Zn:LiTaO3 repoled channel waveguides are reported. The measurements are made at 0.633-mum wavelength using a Fabry-Perot interferometer. The waveguides were produced by diffusion from the vapor phase at a temperature above the Curie temperature. For full recovery of the Pockels effect, an electric field of approximately 200 V/cm is needed during repoling. The measured values of r13 and r33 at 32-MHz modulation frequency are 7.2 and 30.3 pm/V, respectively. The difference between unclamped and clamped coefficients are comparable to those from bulk crystals. Measurements are also made on Ti:LiNbO3 waveguides that did not require repoling and good agreement with bulk crystal values are obtained.
