Abstract

Quantum cascade lasers (QCLs) have been deeply studied structures. We’ll discuss the level of maturity of this technology. In particular we will highlight the main challenges in material production, including growth and process. We’ll show latest results in development of gas sensors at mirSense, as well as products for defense applications. We’ll show why photoacoustic is a perfect match for QCLs, and explore the fundamentals of this sensing technology. Then we’ll say a word on more advanced concepts using such laser technology like chaotic communication for which QCLs have been recently studied.
