Paper Abstract

The combination of silicon and nanotechnology offers the possibility to design ultrafast silicon electro-optic switches with speeds of the order of 100 GHz. The design procedure for an ultrafast silicon electro-optic switch with the addition of photonic crystals is presented. The material medium selected for propagation of the optical signal through the switch is silicon nanocrystals in silica. A patterned slot waveguide with one-dimensional photonic crystals is proposed as the preferred slow light waveguide to be used in the design of the electro-optic switch. The ultrafast quadratic electro-optic effect or Kerr effect is the physical effect utilized, and its analysis for slot waveguides is discussed. The optical structure analysis of the electro-optic switch using a ring resonator is presented and it is shown theoretically that the use of a slow light waveguide in the ring resonator can reduce the required externally applied electric field or the radius of the ring resonator.
