Abstract

The process of repolarization of a LiTaO3 crystal by e−beam lithography was studied. The process of fabrication of ferroelectric domains with domain width of 1 μm was demonstrated. It was shown that in the 127° Y′−cut of a ferroelectric LiTaO3 crystal the ferroelectric domains is formed at the angle of 37° the crystal surface and growth along polar axis Z from negative surface to positive surface Z.
