Nonlinear Group IV photonics based on silicon and germanium: from near-infrared to mid-infrared

Group IV photonics hold great potential for nonlinear applications in the nearand mid-infrared (IR) wavelength ranges, exhibiting strong nonlinearities in bulk materials, high index contrast, CMOS compatibility, and cost-effectiveness. In this paper, we review our recent numerical work on various types of silicon and germanium waveguides for octave-spanning ultrafast nonlinear applications. We ...

Optical bandgap engineering in nonlinear silicon nitride waveguides.

Silicon nitride is a well-established material for photonic devices and integrated circuits. It displays a broad transparency window spanning from the visible to the mid-IR and waveguides can be manufactured with low losses. An absence of nonlinear multi-photon absorption in the erbium lightwave communications band has enabled various nonlinear optic applications in the past decade. Silicon nit...

Optical 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...

Integrated Nonlinear Optics in Silicon Nitride Waveguides

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...
