Paper Abstract

Surface corrugations with periodic of 2 micrometers and a depth of approximately 150 nm have been fabricated in lithium tantalate (LiTaO3) monocrystal wafers. Morphologies of the corrugations were studied with an atomic force microscope. These corrugations were first produced by a single excimer laser pulse through a diffractive optical element, and the optical quality of the periodic structures is demonstrated by its characteristics as a gratings coupler in a LiTaO3 planar waveguide.
