Highly-Nonlinear Silicon Photonics Slot Waveguide 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). Horizontal Slot Waveguides for Silicon Photonics Back-End ... The work demonstrates an alternative solution to costly silicon-on-insulator photonics. The proposed solution uses bulk silicon wafers and thin film deposited waveguides. Back-end deposited horizontal slot grating couplers and waveguides are realized by multi-layers of amorphous silicon and high-k materials.

Silicon Photonic Waveguides and Devices for Near -… B. Slot waveguides Slot waveguides (Fig. 4) can enhance the electric field amplitude in the gap region (up to 50 times higher [28]) compared to standard waveguide structures and thus can provide increased sensitivity in future MIR silicon photonics sensors. Recent results for this waveguide type... Slot-waveguide - Wikipedia A slot-waveguide is an optical waveguide that guides strongly confined light in a subwavelength-scale low refractive index region by total internal reflection. A slot-waveguide consists of two strips or slabs of high-refractive-index (nH) materials separated by a subwavelength-scale low-refractive-index (nS)...
