a The experimental setup. The S21 and S11 response for the Si substrate modulator are given in (b) and (c), respectively. The corresponding measurements for the SOI scenario are shown in (d, e). The wavelength of the input signal was 1286 nm and 1300 nm for the Si and SOI substrates, respectively. DC direct current, RF radio frequency, GS ground-signal, SMF single-mode fibre, TLS tunable laser source, SOA semiconductor optical amplifier, LCA lightwave component analyzer.
