نبذة مختصرة : International audience ; We demonstrate low-loss mid infrared photonic integrated components fabricated on a Ge-rich Si 1-x Ge x platform. These devices show broadband operation over a wavelength range of at least from λ ≈ 5.1 µm to λ ≈ 8.6 µm, and comprise waveguides, multimode interference couplers and Mach-Zehnder interferometers.
