Abstract

Z-cut proton-exchanged LiTaO₃ optical waveguides have been fabricated using cinnamic acid and characterized optically. The diffusion constant (D_o) and the activation energy (E_A) were found to be 152.4 micrometers ²/h and 0.34 eV, respectively. The diffusion rate is lower than published data for other proton sources. The effect of annealing on waveguide depth increase could be accurately modeled by a power-law relationship, and the surface index change increases initially before decreasing. The maximum surface index increase for a particular exchange temperature was found to be dependent on the exchange temperature, and the higher the exchange temperature the lower the index increase.
