We present the simulation and design of single-mode e-o modulators based on 1-D photonic crystal micro resonator fabricated in silicon-on-insulator (SOI) (220nm x 445nm) rib waveguides. The device operates by change the refractive index in the resonator microcavity region produce shifting in center wavelengthof the transmission peak. The refractive index in the microcavity is varied by using the free-carrier dispersion effect. The carrier density is modulated by a p-i-n diode formed about the microcavity. The change in refractive index as well as absorption produced from free carrier dispersion was included in the simulation to analyze the performance of the modulator. The device has been modeled and analyzed using 3D simulation software based on FDTD method.
