Mid-Infrared Platforms for Chemical Sensing

For small gas systems using arrays of QCL sources, we have developed two distinct technology platforms for the fabrication of AWG, with more than 35 inputs in (i) the 3μm-8μm band for SiGe 40 cores cladded with Si and (ii) the 8-12μm band for Ge cores cladded with SiGe 20 .
