Abstract :
Lithium niobate micro-resonators have been fabricated by surface tension reshaping of pre-defined surface microstructures produced at temperatures close to the melting point. Surface-tension-reshaping produced micro-resonator structures with ultra-smooth side surfaces while maintaining the useful crystalline properties. Preliminary optical characterisation on non-optimized structures yielded a Q factor of 5600 at a free spectral range of 4.55nm.
