Abstract
Low-loss proton-exchanged planar waveguides have been fabricated in z-cut LiNb03 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/mm. The propagation loss was typically around 1 dB/cm. The diffusion constant D0 and the activation energy Q for the proton exchange process were found to be 7.02 x107 mm2/hr and 75.58 kJ/mol, respectively.
