Paper Abstract

An electrically induced Bragg ReflectorModulator 2.5 mm long has been designed in InP/InGaAsP rib waveguide. By means of an in house code based on a suitable simulation strategy which takes advantage of state-of-the-art electronic simulator such as Silvaco/ATLAS and a general purpose FEM solver such as Comsol Multiphysics, predictions of DC response the transient analysis had been make. The code allows us to use the same grid to evaluate all the quantity of interest, the effective refractive index included. The simulations results show that such a modulator can theoretically reach ultra 40 GHz switching speed.
