## Abstract Two kinds of groove structure for shortening and broadening the coupling lengths of Ti:diffused LiNbO~3~ directional couplers are presented. The coupling lengths as functions of the depth, width, and spacing of the grooves were numerically calculated. The results show that the maximum s
