The research activity is focused on modelling, theoretical analyses and numerical simulations of Quantum Cascade Lasers (QCLs). The objective is to provide a decription of the phenomena leading to soliton formation in such devices, and to link the above phenomenologiy to the formation of optical frequency combs (OFC) associated to the the optical field profile in the frequency domain. Studies are carried on, concerning the tailoring of soliton shape, soliton motion and soliton clustering in order to a) control the pulsed dynamics and information associated and b) model the OFC distribution. QCL dynamics is also studied in configurations with optical feedback within regimes of self-mixing interferometry, applied to subdiffractive imaging, sensing and emission control In collaboration with the Polytechnic of Turin, the Italian Institute of Techonology (IIT-Milan), the CNR-Nanoscience Institute, the M.I.T. (U.S.A.), the University Cote-d’Azur (F) and the Technical University of Wien (A)
