MIREGA

A patent application that Pr. Jakob Reichel and Dr. Romain Long prepared with Sorbonne Université’s TTO Lutech attracted the attention of an experienced optical technology entrepreneur, and the idea gathered momentum. Following the successful first demonstration of a prototype detecting CO2 and an in-depth market study, the startup company Mirega SAS has been created in early 2023 to bring FFP gas analyzers to the market.

In parallel with Mirega’s product development, research on FFP-enabled, high-performance trace gas analysis continues in our group. We are pushing FFP technology further to the mid-infrared into the “molecular fingerprint region”, where much stronger molecular transitions enable still more sensitivity and precision. Furthermore, with their short length and extremely large free spectral range, FFP cavities explore new terrain in cavity-enhanced spectroscopy and open the door to novel modulation and signal extraction techniques.
