2. Highly Nonlinear SOI Slot Waveguides and Optimization for Maximum Nonlinearity The structure of the highly nonlinear silicon on insulator slot waveguide is shown in Fig. 1(a). Its core consists of two silicon (Si) ribs on a silicon buffer (SiO2). The slot waveguide is filled and covered with a Kerr-type nonlinear organig cladding (NL). 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
The importance of exploring nonlinear effects in Silicon-on-Insulator (SOI) slot optical waveguides is discernible from the facts that, it is CMOS technology compatible, thus ensuring low-cost large-scale integration, moreover, this structure of optical waveguides mingle the advantages of both silicon and silica to explore the promising ...
Design Optimization of Silicon-on-Insulator Slot-Waveguides ... An approach for design optimization of the geometrical parameters of silicon-on-insulator slot-waveguides for electro-optical modulators and biosensors is presented. Theoretical investigations of field confinement factors and effective nonlinear areas for different slot-waveguide structures are critically analyzed and thoroughly calculated. Analysis of Kerr nonlinearity enhancement in silicon nitride ... To enhance the nonlinear Kerr effect in silicon nitride waveguides and to increase, specifically, the nonlinear phase shift in silicon nitride, the slow-light effect is employed in this paper. The design of one-dimensional silicon nitride slow-light waveguides is investigated to decrease the required length for achieving certain NLPS.
