    A novel LiNbO3 modulator based on Si2N2O substrate is proposed. Using the finite element method,the proposed modulator has been analyzed. The optimum structure parameters of the novel modulator are obtained. The modulator operates with a 3 dB optical bandwidth of 120 GHz,a half-wave driving voltage of 3.5 V,and characteristic impedance of 50.32Ω. The results show that broad bandwidth and low half-wave voltage can be achieved simultaneously. It is a promising candidate for future ultra-high-speed optical fiber transmission system.
