Recent works towards the development of Ge-rich SiGe photonic integrated circuits for on-chip mid-IR spectroscopy will be presented. First, the demonstration of ultra-wideband passive circuits will be discussed, followed by the first proofs of concepts towards the realization of efficient wideband active devices. The combination of on-chip integrated spectrometers with on-chip mid-IR sources will provide a solid basis for the development of a competitive mid-IR integrated platform from 3 to 15 µm wavelength.
