متن کاملAll-optical switching in silicon photonic crystal waveguides by use of the plasma dispersion effect.
Silicon photonic crystals offer new ways of controlling the propagation of light as well as new tools for the realization of high-density optical integration on monolithic substrates. However, silicon does not possess the strong nonlinearities that are commonly used in the dynamic control of optical devices. Such dynamic control is nevertheless essential if silicon is to provide the higher leve...
متن کاملBackscattering in silicon photonic devices
We report on the backscattering induced by sidewall roughness in silicon on insulator optical nanowires, its dependence on the waveguide geometrical and optical parameters and its impact on silicon photonic devices. In silicon ring resonators cavity-enhanced backscattering, increasing with the square of the resonator’s finesse, emerges as a severe
