a RF s-parameter characterization featuring a −3 dB and −6 dB bandwidths of 7.1 GHz and 9.9 GHz respectively. S21 transmission coefficient of the scattering matrix. Inset shows the S11, reflection spectrum of the modulator. b Optical spectrum at the output of the modulator for various input RF frequencies. The measurement at 2.5 GHz which is within the resonator linewidth is used in the Pockels coefficient extraction.
