AUTHOR=Finot Christophe TITLE=A Peregrine Soliton-Like Structure That Has Nothing to Deal With a Peregrine Breather JOURNAL=Frontiers in Physics VOLUME=8 YEAR=2021 URL=https://www.frontiersin.org/journals/physics/articles/10.3389/fphy.2020.590415 DOI=10.3389/fphy.2020.590415 ISSN=2296-424X ABSTRACT=

We report on experimental results where a temporal intensity profile presenting some of the main signatures of the Peregrine soliton (PS) is observed. However, the emergence of a highly peaked structure over a continuous background in a normally dispersive fiber cannot be linked to any PS dynamics and is mainly ascribed to the impact of Brillouin backscattering.
