Abstract

Most comb research is focused on the generation of pulses. However, frequency combs can also exhibit a very different behavior that is characterized by a continuous output intensity – the frequency modulated (FM) comb regime. Here, we present our theory including a new master equation to describe the involved physical mechanisms and explain which conditions need to be fulfilled to generate self-starting FM combs. Using our new insights we will discuss experimental observations of FM combs in quantum cascade lasers, as well as lasers with slower dynamics, such as interband cascade, quantum well and quantum dot laser.
