Abstract

Proton-exchanged planar waveguides were demonstrated in Z-cut LiNbO3 using toluic acid as a new organic proton sources. These waveguides exhibit a propagation loss of around 1 dB/cm, and a step refractive index profile with an index increase of 0.124 measured at 0.663 μm. The diffusion rate was found to be lower than those obtained using the popular benzoic and phosphoric acids.
