Abstract
Temporal cavity solitons (CS) in Kerr resonators offer a potential alternative to mode-locked lasers concerning the generation of ultracoherent pulse trains, guaranteeing high coherence between pulse trains and a highly coherent continuous wave lasers. In this work, we report the first experimental observation of single coherent picosecond pulses in a fiber active optical parametric oscillator driven in continuous wave.

After a master's in physics of Matter with a thesis on Photoacoustic sensors for pollutant detection (Universita' degli Studi di Bari - Italy), he completed his PhD in the U. K. (University of Southampton) with a thesis concerning the functionalization of silica fibers for generation of second order nonlinear phenomena. His main research goal is to use periodically poled fibers for the implementation of miniaturized laser sources for telecommunication and spectroscopy applications. In the last 5 years he worked at OPERA-Photonique group of Universite' libre de Bruxelles as Marie Curie fellow and FNRS charge de recherche fellow. His activity has been mainly dedicated to the generation of phase coherent pulse trains in fiber optical parametric oscillators as an alternative to settled technological platforms such as mode-locked laser. He recently moved to University of Lille - PhLAM laboratories to keep working on fiber OPOs in Fabry-Perot configuration adopting periodically poled fibers.
