Summary :

The effect of annealing on the electrooptic constant r33 in the proton-exchanged optical waveguides on three types of lithium niobate crystals: undoped, titanium-indiffused and MgO-doped, are investigated. The exact estimation shows that the deterioration of electrooptic constant is recovered by annealing; the best in undoped, then titanium-indiffused and the worst, MgO-doped.
