We fabricate a 4-mm-long silicon–organic hybrid waveguide with a record nonlinearity coefficient of g 13105 W21 km21 and perform all-optical demultiplexing of 170.8 Gb s21 to 42.7 Gb s21. This is—to the best of our knowledge—the fastest silicon photonic optical signal processing demonstrated. One-dimensional photonic crystal slot waveguide for ... ) of 100 nm. The 1D PC slot waveguide sits on top of a silicon dioxide layer and is covered with EO polymer (SEO 125 Soluxra, LLC., n 1.63). Figure 2(a) shows the simulated photonic band dia- gram of the quasi-transverse-electric (TE) modes of the 1D PC slot waveguide using the 3D plane-wave expansion method.

To conclude, we demonstrate slow light operation with NDBP as high as 0.156 in silicon slotted photonic crystal waveguides with a transmission level only 5 dB lower than the one of reference SOI strip waveguides, including the in/out coupling stages that are used to excite the slow light slot optical mode.
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 ... Frontiers | Low-Loss Slot Waveguides with Silicon (111 ... We demonstrate low-loss slot waveguides on silicon-on-insulator (SOI) platform. Waveguides oriented along the (11-2) direction on the Si (110) plane were first fabricated by a standard e-beam lithography and dry etching process. A TMAH based anisotropic wet etching technique was then used to remove any residual side wall roughness. Using this fabrication technique propagation loss as low as 3 ...

Different Configurations of Silicon Waveguides. The crux of the silicon waveguide lies with the high contrast of the refractive index, around a 50% difference.However, recent work confined the energy in the lower-refractive-index slot neighbored by the high-refractive-index slabs, inherently helping to...
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. The silicon typically lies on top of a layer of silica in what ...
