Free-space communication in the mid-IR domain has many potential applications, but security is still challenging. Here, the authors use chaos synchronization in a QCL-based free-space link as a way to increase privacy of such transmissions.

Spectroscopic techniques based on Distributed FeedBack (DFB) Quantum Cascade Lasers (QCL) provide good results for gas detection in the mid-infrared region in terms of sensibility and selectivity. The main limitation is the QCL relatively low tuning

Mid-infrared free-space optical communication has a large potential for high speed communication due to its immunity to electromagnetic interference. However, data security against eavesdroppers is among the obstacles for private free-space communica

We demonstrate a mid-infrared spectrometer based on a quantum cascade laser operated in the intrapulse mode coupled with a custom dense pattern multipass cell. Detection in the range of hundreds of ppm to a few percent has been achieved due to a spec

We demonstrate an all-optical square modulation in a room-temperature quantum cascade laser with cross-polarization reinjection. The duty cycle of the pattern is controlled by varying the components of the polarization, paving the way for integrated
