Paper Abstract
A theoretical study of multimode operation regimes in quantum cascade lasers (QCLs) is presented. It is shown
that the fast gain recovery of QCLs promotes two multimode regimes: One is spatial hole burning (SHB), and
the other one is related to the Risken-Nummedal-Graham-Haken (RNGH) instability predicted in the sixties. A
model that can account for coherent phenomena, a saturable absorber and SHB is developed and studied in
detail both analytically and numerically.
