We report results of an investigation studying the domain inversion kinetics of lithium niobate when electric field poling using laser-machined topographical electrodes. Inversion is shown to begin with a single nucleation spike and the domains evolve in a unique fashion governed by the topographical structure. We also demonstrate control of the resulting domain widths when poling using this technique. The results presented have implications for rapid prototyping of chirped and aperiodic domain structures in lithium niobate.
