Abstract:
Silicon-based photonic crystal integrated circuits, i.e. nanostructured silicon-based wafers in which the periodicity of the refractive index is exploited to tailor the on-chip light confinement and propagation, can be exploited to strongly enhance the intrinsic nonlinear properties of this material. In this talk we will give an overview of our past and ongoing research efforts in this field. Specific topics that will be discussed are: all-optical switching in photonic wire nanocavities at ultra-low powers [2,3], strongly enhanced harmonic generation [4,5] and optical bistability.
