Substrate removing technique is proposed in silicon Mach–Zehnder modulator (MZM) to improve the electro-optic bandwidth. Based on this technique, a MZM with 3 dB electro-optical bandwidth of 55 GHz achieved at 5 V reverse bias for first time. The V[Formula: see text] L 1.3 text]cm an on-chip insertion loss 5.4 dB. substrate reduces electrode transmission loss, achieves group index matching and realizes 50 [Formula: impedance matching, simultaneously. In work, we experimentally demonstrate BPSK modulation based baud rate up 56 Gb/s.
