a Experimental spectra at different voltages Vin applied to MZI 1 for the Pout,2/Pin,1 ratio. The gray window represents the range of wavelengths that were averaged to create the dataset21,23. b Resulting Pout,2/Pin,1 power ratio curve associated to MZI 1, obtained by averaging the spectra in the gray box.
