Abstract
We demonstrated proof-of-concept Ge ring modulator by carrier injection on the Ge-on-insulator (GeOI) platform. Owing to the strong optical confinement in Ge rib waveguide, the optical modulation with 13 dB extinction ratio was obtained by optical phase shift induced by 1 mA current injection.
