Pulse generation by on-chip dispersion compensation at 8 μm wavelength

The mid-infrared spectral region holds growing importance for applications such as gas sensing and spectroscopy, and compact ultrashort pulse laser sources are essential to enable these applications. However, the fast gain dynamics of intersubband transitions hinders the direct generation of pulses from quantum cascade lasers (QCL). In this work, based on a collaboration between C2N (CNRS/Universite Paris Saclay), ETH Zurich and Politecnico di Milano, we take advantage of …
