Abstract

Lattice guiding is used to synthesize preferentially oriented thin films of (Sr_0.6Ba_0.4)Nb₂O₆ by RF magnetron sputtering, with the film-substrate crystallographic relationship determined. These ferroelectric thin films guide light at 532 and 633 nm and have a single domain structure that can be written with permanent, sub-micron, anti-parallel domains.
