Abstract :
Optical waveguides in Z-cut MgO:LiNbO3 fabricated by the proton-exchange process using phosphoric acid have been characterised. The waveguide exhibits a graded index profile with a surface index change of 0.145 measured at 0.633 mu m. The diffusion rate is slower than that of undoped LiNbO3.
