Abstract

We review our recent results on integration of lasers, detectors and microfluidic channels on silicon and germanium based mid-infrared photonic circuits, as well as initial sensing experiments for medical and gas sensing applications. Wideband devices, such as waveguides, couplers, splitters and detectors are required for mid-IR absorption spectroscopy. We show that such Si and Ge devices can operate over large spectral bands.
