NanoMIR is a world leader in III-Sb technology, i.e. the family of III-V compounds based on GaSb, InAs, AlSb, InSb, their alloys and their heterostructures. It aims at developing this technology and its applications.
The antimonides (III-Sbs) are III-V semiconductors with effective band gaps particularly well suited to the mid-infrared (mid-IR ~ 2–12 µm), a wavelength range which exhibits transparence windows of the atmosphere as well as strong absorption lines from many gas species. The mid-IR is thus very well suited to develop a variety of applications with important societal impact such as gas analysis (pollution or process monitoring, physics of gases, of the atmosphere,…), medical applications (surgery, diagnosis,..), free-space communications, but also security- and defense-related applications (counter measures, detection of toxic or explosive species, night vision,…).
For the last ten years, nanoMIR has been mainly focusing on developing mid-IR optoelectronic devices (lasers, photodetectors, highly-coherent laser sources) for these applications. It has achieved a number of breakthroughs which can be traced back in the list of publications.
Another objective of the group is to perform more fundamental studies and to explore the full potential of the III-Sb technology. So, activities on the integration of the III-Sb devices with the Si technology, on all-semiconductor plasmonics or on gas sensors have recently appeared. On the other hand, new exploratory topics (Optical Parametric Oscillations, topological insulators, concentrated photovoltaics,…) are emerging.
