Quantum cascade lasers
mirSense’s quantum cascade lasers are helping to
make multi-gas spectrometers smaller and more
accessible without compromising on performance.mirSense was founded in 2015 to commercialize
sensor solutions based on a quantum cascade laser
(QCL) technology developed by the CEA, Alcatel,
and Thales in research at the III-V Lab. The lasers
are the key component of mirSense’s cigarettepack-sized
multi-gas spectrometers. Although they
are a hundred times more compact than traditional
spectrometers, mirSense’s solutions do not
compromise on performance. Capable of detecting
a number of different gases, the sensors are precise,
sensitive, and selective.
The company chose photoacoustic rather than
optical detection technology for its spectrometers,
a choice that will allow for further miniaturization
and silicon integration to reduce costs, two key
advantages for penetrating high-volume markets.
The mirSense-CEA joint R&D lab is working to
support this go-to-market strategy.
mirSense is currently targeting industrial markets
(emission gas detection, process control, and leak
detection) and plans to expand into other markets
like automotive emissions testing, indoor air quality,
and onboard automotive sensors. The company also
sells high-power quantum cascade lasers to the
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
