Abstract

This Letter presents, to the best of our knowledge, the first hybrid --based tunable microring resonator where the waveguide is formed by loading a strip on an electro-optic (EO) material of -cut thin-film . The developed hybrid - microring exhibits a high intrinsic quality factor of 1.85×10, with a ring propagation loss of 0.32 dB/cm, resulting in a spectral linewidth of 13 pm, and a resonance extinction ratio of ∼27   within the optical C-band for the transverse electric mode. Using the EO effect of , a 1.78 pm/V resonance tunability near 1550 nm wavelength is demonstrated.
