1. A device, comprising:

  • an optical resonator configured to support whispering gallery modes and comprising a plurality of sectors that are optically nonlinear and each exhibit an electro-optical effect, wherein nonlinear coefficients of two adjacent sectors are oppositely poled; and

    an electrical waveguide located relative to the optical resonator to guide an electrical oscillation signal into the optical resonator to spatially overlap with the whispering gallery modes and to modulate an index of the optical resonator via the electro-optical effect.
