Paper Abstract

We propose the light switching technique by photonic induced carriers injection in a silicon guiding layer. The designed Photonic crystal Bandgap (PBG) waveguide and the 32x32 channel Photonic Multimode Interference structure are utilized to construct the all-optical switching device. The pumping light generates free carrier density to change the silicon local material refractive index, so we simulate light switching by the control of pumping light. In this paper the beam propagation method (BPM) is applied to simulate the wavelength division and the optical signal switching characteristics. The Finite Difference Time Domain Method (FDTD) is used to analyze PBG characteristics. The simulations demonstrate the possibility of achieving an all-optical switching device.
