Abstract

Optical domain inversion effects on the performance of electro-optic devices in Ti-indiffused C-cut LiNbO3 are studied. The C- surface was found to be considerably more immune to domain inversion than the C+ surface under similar diffusion conditions. The extent of domain inversion was found to depend on the diffusion temperature, time, initial Ti film thickness and waveguide width. Lower electro-optically induced phase mod lation was observed in the drive voltage in Mach-Zehnder interferometers fabricated on C-1- substrates compared to that of C- substrates under the same voltage drive. The increase in crosstalk levels and change in the switching behavior of directional couplers attributable to domain inversion are also discussed.
