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 ... Silicon photonics - Wikipedia Silicon photonics is the study and application of photonic systems which use silicon as an optical medium. The silicon is usually patterned with sub-micrometre precision, into microphotonic components. These operate in the infrared, most commonly at the 1.55 micrometre wavelength used by most fiber optic telecommunication systems. OSA | Highly efficient nonlinearity reduction in silicon-on ... Vertical slots are used to reduce the nonlinearity of silicon-on-insulator waveguides. In properly designed slot waveguides, approximately 50% of the optical power can be confined in the air-slot and air-cladding region. Compared with a strip waveguide, a factor greater than 15 times more reduction ... Slot-waveguide - Wikipedia
For strip waveguides, the waveguide width was 450 nm. For slot waveguides, we designed three different slot widths of 100, 150, and 200 nm with 225-nm wide silicon arms on both sides.Nonlinearity of optimized silicon photonic slot waveguides.
Low-Loss BaTiO3–Si Waveguides for Nonlinear Integrated ... Barium titanate (BaTiO3) has become an attractive material to extend the functionalities of the silicon photonics platform because of its large Pockels coefficient of more than 1000 pm/V. BaTiO3 integrated epitaxially on silicon-on-insulator substrates can be structured in passive and electro-optic silicon photonic devices using slot-waveguide geometries, both of which have been demonstrated. Potential of slot waveguides for silicon-based optical ... Potential of slot waveguides for silicon-based optical interconnects Yehea Ismail, Hosam Mekawey, Rania Gamal and Mohamed A. Swillam Compact dielectric and plasmonic slot waveguides have low loss characteristics and can be fabricated in a CMOS-compatible manner, and are thus suitable for integration in modern integrated circuits. Nonlinear Photonics with Optical Waveguides The combination of dispersion and nonlinearity leads to a variety of nonlinear phenomena with useful applications. Optical bers used often in practice because their low losses allow long interaction lengths. Planar waveguides made using silicon, silicon nitride, or chalco-genide glasses are attracting attention in recent years.

In this theoretical study, we show that the use of optimized horizontal silicon photonic slot waveguide structures could enable the realization of devices with a nonlinearity coefficient of more than 2×10 7 W −1 km −1. Low-nonlinearity and low-loss silicon slot waveguides with ... We demonstrate low-loss silicon slot waveguides filled with single and dual atomic layer deposited oxide layers. Propagation losses less than 5 dB/cm and 8 dB/cm are achieved for the waveguides with single (Al 2 O 3) and double (Al 2 O 3-TiO 2) layers, respectively.The devices are fabricated using low-temperature CMOS compatible processes. Angled sidewalls in silicon slot waveguides: conformal ... 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].
