Abstract: We investigate the domain structure obtained, on overpoled both sides polished z-cut Lithium Niobate crystal sample by applying an electric field on periodic liquid electrodes. Lithium Niobate sample was spatially patterned with photoresist by use of interference photolithographic process. The sample was then etched in a mixture of hydrofluoric and nitric acid to reveal the reversed domains. The different etch rate of the two Opposite z faces of the crystal domains allowed to measure the surface profile of the sample by using a profilometer. Overpoling the crystal caused the appearance of high density and submicrometer spacing single dot domains vertically aligned along the direction of the interference fringes in the patterned region.
