Existence and dynamics of pairs of temporal cavity solitons weakly-bound through kelly sidebands in a passive optical fiber resonator

2015

We report experimental observations of weaklybound states of temporal cavity solitons, with separations of 10 soliton widths and beyond, in a 100-m single mode fiber cavity. Bound state dynamics has been studied using the real time dispersive Fourier transform technique for roundtrip-byroundtrip measurements. Temporal oscillations in the cavity soliton background, associated with the presence of Kelly sidebands, have been identified as the binding mechanism.

Dissipative polarization domain walls as persisting topological defects

2018

We experimentally demonstrate the existence of dissipative polarization domain walls in a normally dispersive Kerr resonator. We excite and trap them with appropriate external signals thus realizing an all-optical buffer for topological data.

Buffering optical topological data using passive Kerr resonators

2018

We experimentally demonstrate the existence of dissipative polarization domain walls, in a normally dispersive Kerr resonator. Through deterministic manipulation of the laser driving the resonator, we achieve systematic excitation and locking of the domain walls.

Imperfect symmetry breaking

2018

By considering a nonlinear resonator driven by an elliptically polarized beam, we study experimentally the robustness of spontaneous symmetry breaking to controlled asymmetries. In particular, we reveal that different asymmetries can balance each other.
