Abstract :
Thermal treatment of micro-structured lithium niobate, at temperatures close to the Curie point, induces preferential surface melting and re-crystallization. This process yields ultra-smooth single crystal superstructures suitable for fabrication of low scattering loss photonic micro-components.
