Abstract:
Low dissipation integrated frequency combs are ideal candidates to realize miniaturized spectrometers without moving parts and hence are of great interest for integrated photonics. After reviewing frequency comb generation in interband cascade lasers (ICLs), the nonlinear dynamics and performance limiting mechanisms of ICLs will be discussed. A newly developed k-space resolved non-equilibrium carrier transport model combined with experimental studies enables us to explore different loss mechanisms, as well as to explore the reasons, why passive mode-locking of ICLs for short pulse generation remains challenging.
