Group IV Photonics for the Mid-Infrared

In this paper we present SOI, suspended Si, and Ge-on-Si photonic platforms and mid-IR passive and active devices based on these platforms. We demonstrate low loss waveguides, splitters, filters, interferometers and spectrometers in different material platforms. Mid-infrared detection using defect engineered silicon waveguides is reported at the wavelength of 2-2.5 µm. All optical modulation in Ge is also analyzed. Finally, theoretical investigation of electroabsorption and electrorefraction in Ge is reported.
