Spontaneous Raman scattering in a silicon wire waveguide

We report spontaneous Raman scattering at 1550nm in an SOI strip waveguide with cross-sectional area 0.1µm2. The tight optical confinement permits efficient Raman conversion for small coupled pump powers (1435nm) of <50mW.

Nonlinear optics in Si wires on an SOI platform

We discuss measurement of the nonlinear-optical properties of Si-wire waveguides and the design of these wires for use in on-chip waveguide applications.

Slow Light in Photonic-Crystal Waveguides and Cavities

Coupling losses and high-order dispersion in the slow-light regime of photonic-crystal (PhC) waveguides are investigated by utilizing an integrated Mach-Zehnder interferometer. Furthermore, PhC cavities coupled to photonic-wires through surface-states are experimentally characterized.

Dispersion Engineering in Silicon Photonic Wires Using Thin Si 3 N 4 Conformal Dielectric Coating

We investigate numerically dispersion engineering in silicon photonic wires using conformal Si3N4coatings. We analyze the impact of coating thickness upon the group-velocity-dispersion and effective waveguide nonlinearity, and show broadband four-wave-mixing gain in engineered waveguides.
