Abstract

A novel electro-optical modulator using GeO₂ doped silica waveguides based on silicon substrate is proposed. The modulator is analyzed and designed with the finite element method. The simulation results show that the designed modulator operates with a 3dB optical bandwidth of 56.6GHz, a half-wave voltage of 8.9V and a characteristic impedance of 51.8Ω at 1310nm wavelength. The presented modulator can be fabricated easily using Si-based very large-scale integrated technology and is very suitable for optoelectronic integrated circuits.
