Abstract

A novel fiber type traveling-wave modulator is developed. The finite element method (FEM) has been used to analyze the performance of the proposed modulator with coplanar waveguide (CPW) electrode structures. The optimized structures of the traveling-wave modulator are obtained. The results show that the novel modulator has a 3dB optical bandwidth of 112GHz, a half driving voltage of 2.7V, and characteristic impedance of 51.2Ω at 1.55μm wavelength.
