The C2N is coordinating CIRCULIGHT, a Horizon Europe project aimed at revolutionizing integrated photonics.

The C2N coordinates CIRCULIGHT (Circulating Light on Any Photonic Platform), a project funded by the European Innovation Council under the Horizon Europe EIC Pathfinder programme. Bringing together nine partners from six European countries — including seven research institutions and two industrial partners — the project started in April 2024 and will run for 42 months. Overcoming a major technological bottleneck in …

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 …
