Abstract
We review our work on SOI and Ge-on-Si PICs for the mid-infrared, covering the 2-8 m wavelength range. We demonstrate the integration of III-V semiconductors on the SOI platform for 2-4m wavelength range integrated lasers and spectrometers, as well as demonstrate tunable quantum cascade lasers by butt-coupling a 5 m wavelength range quantum cascade gain chip to a Ge-on-Si tunable filter. Chip-based mid-IR spectroscopic sensors (based on NDIR spectroscopy, photo-thermal spectroscopy and absorption spectroscopy) will be discussed as well.
