(a) Change of effective refractive index vs. bias voltage. (b) Change of maximum output intensity under different coupling gaps g. (c) The tuned resonance wavelength and the obtained amplitude and phase response for the coupling gap g = 150 nm. (d) Detailed intensity changes and phase shifts vs. bias voltage under g = 150 nm and λ = 1552.4 nm.
