  • Abstract
    Recent results provided experimental evidence that losses in bent Ti:LiNbO/sub 3/ waveguides can be drastically reduced by using additional titanium and magnesium oxide. We determine an optimization procedure for the index profile in curved sections. The beam propagation method indicates that in optimized bends, losses are orders of magnitude below those of conventional bends. Tolerances in mask alignment and in deposited film thickness are estimated to be well compatible with present technology.<>
