Hybrid Si - LiNbO 3 electro-optic tunable ring resonators have been proposed and demonstrated as a path to achieving ultracompact and high-speed electro-optic devices. Free standing single crystal LiNbO 3 microplatelets ( mm long and 1 μm thick) were obtained from a z-cut LiNbO 3 substrate by ion implantation and thermal treatment. The platelets were transferred and thermally bonded on top of Si resonators that were fabricated in a Si-on-insulator platform by a 0.18 μm standard complementary metal-oxide-semiconductor process. For the hybrid microring resonator, a free spectral range of 16.5 nm , a finesse F of 1.67 × 10 2 , a Q-factor of 1.68 × 10 4 , and an effective r coefficient of 1.7 pm / V were achieved for the TE mode. These values are in good agreement with the calculated results.
