A directional coupler with nickel-indiffused LiNbO wa¨e-3 guides was fabricated successfully for the first time. Moreo¨er, the coupling characteristics of an Ni:LiNbO directional coupler, including 3 the coupling coefficient and coupling length, were exactly measured by the multiple wa¨eguide array

The coupling ratio of directional couplers in Z-cut Y-propagation and X-cut Z-propagation LiNbO3 crystals was adjusted by laser ablation. The coupling ratio change is more e cient for the TM-mode of Z-cut couplers. The method can be used to correct the uncertainty of the coupling ratio for direction
