A broadband travelling-wave electro-optical modulator based on teflon substrate is proposed. Finite element method is
employed to analyze the performance of the proposed modulator. The relations between the structure parameters and the
properties of the modulator have been investigated. The optimized structure parameters of the modulator are obtained.
The results show that the modulator has wide modulation bandwidth, low half-wave voltage, and perfect impedance
