Abstract

Low-loss proton-exchanged planar waveguides have been fabricated in z-cut LiNbO3 using a new organic proton source: toluic acid. These waveguides exhibit a step refractive index profile with a surface index increase of 0.124 measured at 0.633 μm. The propagation loss was typically around 1 dB/cm. The diffusion constant Do and the activation energy Q for the photon exchange process were found to be 7.02 × 107 μm2/hr and 75.58 kJ/mol, respectively.
