Abstract :
Summary from only given. A method for the construction of periodically inverted ferroelectric domains near the surface region of congruent LiNbO/sub 3/ and LiNbO/sub 3/ waveguides has been investigated. For periods as short as 1 /spl mu/m the domain inverted area overlaps well with the guided optical fields in these structures presenting a promising route for the fabrication of efficient first order QPM nonlinear optical devices. Further work on the conditions for the optimization of the mark-to-space ratio for the periodic domains as well as characterization of the waveguide-SHG devices is under way.
