Nonlinear silicon photonics - IOPscience Silicon and silicon-based materials have strong optical nonlinearities which are enhanced in integrated devices by the small cross-section of the high-index contrast silicon waveguides or photonic crystals. Here the photons are made to strongly interact with the medium where they propagate. This is the central argument of nonlinear silicon ... Slot-waveguide - Wikipedia Slot-waveguide. A slot-waveguide is an optical waveguide that guides strongly confined light in a sub wavelength -scale low refractive index region by total internal reflection . A slot-waveguide consists of two strips or slabs of high-refractive-index (n H) materials separated by a subwavelength-scale low-refractive-index (n S)... Silicon photonics - Wikipedia Silicon photonics. The presence of nonlinearity is of fundamental importance, as it enables light to interact with light, thus permitting applications such as wavelength conversion and all-optical signal routing, in addition to the passive transmission of light.
Effective nonlinearity and FOMn2 /α2 in silicon nanocrystal filled slot waveguides with wr =160 nm and h = 260 nm, as a function of wsb at different ws from 40 nm to 120 nm. Silicon nanocrystals are an example of a nanocomposite, which might provide several orders of magnitude higher nonlinearity than SiO2 [15].
