Conclusions and Perspectives, is stable and single-mode again. These regimes are similar to those observed in laser diodes, but they appear at much higher feedback ratios, and the fourth unstable regime is narrower, the QCLs are therefore much more resistant to optical feedback.

It also leads to a different dynamical behavior, and a quantum cascade laser subject to optical feedback can oscillate periodically or even become chaotic.? A quantum cascade laser under external control could therefore be a source with enhanced prop

Quantum Cascade Lasers: High Performance Mid-infrared Sources,This chapter will present the principle of operation and theory of QCLs. The . -factor, key parameter of semiconductor lasers but not well-known in QCLs, will then be defined, before studying in details a specific QCL structure, from which both Fabry-Perot (FP) and distributed feedback (DFB) devices emitting around 5.6 . were fabricated.

Impact of Optical Injection on Quantum Cascade Lasers,After a brief review of the effects of optical injection on a laser diode both in and outside the locking range, this chapter will present a overview of the state of the art on optical injection in QCLs, as well as a numerical study applied to the QCL structure described in the second chapter.
