Terahertz nonlinear conduction and absorption saturation in silicon waveguides
The interaction of terahertz waves with silicon is usually explained using a linear model of conduction in which free carriers respond to the oscillating electric field, leading to absorption. Here we employ a silicon dielectric waveguide to confine and concentrate terahertz pulses, and observe that the absorption saturates under strong terahertz fields. By comparing the response between lightl...
متن کاملInfluence of nonlinear absorption on Raman amplification in Silicon waveguides.
We model the TPA-induced free carrier absorption effect in silicon Raman amplifiers and quantify the conditions under which net gain may be obtained. The achievable Raman gain strongly depends on the free carrier lifetime, propagation loss, and on the effective Raman gain coefficient, through pump-induced broadening.

Integrated optics platforms offer the possibility to implement compact photonic devices for nonlinear optics applications. Modern nanofabrication facilities allow the fabrication of sub-micron-sized waveguide geometries that confine light to reach very high optical intensities. These intensities enable efficient nonlinear processes that are further enhanced by using materials with high nonlinea...
متن کاملNonlinear Optics in Silicon Waveguides : Stimulated Raman Scattering and Two-Photon Absorption
Silicon-On-Insulator integrated optics boasts low loss waveguides and tight optical confinement necessary for the design of nanophotonic devices. In addition, the processing is fully compatible with capabilities of standard silicon foundries. Because of crystal symmetry, silicon does not possess 2 order nonlinear optical effects. However, the combination of nanoscale geometries with the high re...
متن کاملOptical pulse compression based on nonlinear silicon waveguides and chirped Bragg gratings
Due to the growing demand for higher bandwidth, employing optical devices instead of electronic devices in data transmission systems has attracted much attention in recent years. Optical switches, modulators and wavelength converters are a few examples of the required optical devices. CMOS compatible fabrication of these devices, leads to much more growing of this technology. Optical pulse comp...
