Paper Abstract

Frequency combs are ideal candidates to realize miniaturized spectrometers without moving parts. ICLs are perfect for the realization of miniaturized spectrometers, due to their low power consumption and the possibility to build sensitive on-chip detectors using the same epilayer material. Here, we present an overview of our current work on ICL frequency combs. This includes the generation of self-starting frequency combs utilizing their gain nonlinearity, resulting in a dominant frequency modulation similarly to quantum cascade lasers frequency combs. Furthermore, we demonstrate the generation of 3ps pulses with a peak to average power ratio of over 40 via active mode-locking.
