Germanium-on-silicon, mid-infrared waveguides operating up to 11 micron wavelength are demonstrated for the first time, with propagation losses below 5.5 dB/cm. The results indicate that the platform could be suitable for sensing applications in the 8–13 micron atmospheric window of the molecular fingerprint region
