Abstract

Low-loss proton-exchanged planar waveguides in z-cut LiNbO₃ were fabricated and characterized optically using a new proton source: octanoic acid. The waveguide exhibited a step-index profile with an index change of 0.118 measured at 0.633 μ m. The lowest waveguide propagation loss measured was 1.2 dB/cm, and it was reduced further to 0.4 dB/cm after annealing. The diffusion rate and the activation energy using this acid were found to be lower than those reported using other acids.
