The amount of optical feedback originating from a chalcogenide fiber used to couple light from a mid-infrared quantum cascade laser is evaluated experimentally. Threshold reduction measurements on the fibered laser, combined with an analytical study

Precise knowledge of the linewidth enhancement factor of a semiconductor laser under actual operating conditions is of prime importance since this parameter dictates various phenomena such as linewidth broadening or optical nonlinearities enhancement

We have fabricated InP-based coherent quantum cascade laser micro-stripe arrays. Phase-locking is provided by evanescent coupling between adjacent stripes. Stripes are buried into semi-insulating iron doped InP. Lasing at room temperature is obtained

We report on the first experimental chaos synchronization in mid-infrared quantum cascade lasers and subsequently perform private free-space transmission at a bit-rate of 0.5 Mbits/s. The quality of the privacy is assessed with eye diagrams, both at

We present the design, fabrication and the characterisation of compact and widely tuneable MIR source. This device is based on an INP micro-lenses array and on a DFB QCL array. Both of those arrays are designed together to induce a beam combination.
