We describe the fabrication and properties of optical waveguides formed in Z-cut LiTaO 3 by reverse proton exchange Li + -ยปH + in the LiNO 3 melts at 280-340 ยฐC. Surface waveguides, supporting TE modes, as well as the buried waveguides for TM modes have been produced. The diffusion constant D 0 and
