The numerical analysis has been performed by using a finite-difference time domain (FDTD) based simulation tool. The design of the PhC-based MZ Modulator relies on the exploitation of the refractive index tunability of the hydrogenated amorphous silicon (a-Si:H) for the fabrication of PhC waveguides requiring minimum critical technological processes.enconference paper
