Solitons and frequency combs in microresonators: SOLIRING

The SOLIRING network supports the multilateral transfer of knowledge between photonics, physics and applied mathematics.

The SOLIRING research network is funded by the Horizon 2020 Research and Innovation Staff Exchange (RISE) programme of the European Commission.

The research programme focuses on advancing the knowledge about frequency comb generation and soliton formation in the whispering gallery resonators and surface nanoscale axial photonics resonant structures.

Our theoretical and experimental studies aim at the understanding of the open fundamental problems in the physics of the frequency comb generation and at developing new methods and devices that can find applications in the high precision spectroscopy, all-optical processing of information and astrophysics.

The complementary expertise of partners in this network is crucial to tackling the challenging cross-disciplinary problems.
