Grating coupled low loss Ge-on-Si waveguides and multimode interferometers for the mid-infrared

Germanium-on-silicon is a promising platform for planar photonics over the entire mid-infrared range. We report here grating coupled Ge-on-Si waveguides with record low losses of 0.6dB/cm, multimode interferometers and Mach-Zehnder interferometers.
