Decoherence and turbulence sources in a long laser
Amy Roche, Svetlana Slepneva, Anton Kovalev +5
We investigate the turn-on process in a laser cavity where the roundtrip time is several orders of magnitude greater than the active medium timescales. In this long delay limit the…
Critical Slowing Down in a Real Physical System
Mathias Marconi, Karin Alfaro-Bittner, Lucas Sarrazin +2
The behavior of a dynamical system can exhibit abrupt changes when it crosses a tipping point. To prevent catastrophic events, it is useful to analyze indicators of the incoming bi…
Noise-induced broadening of a quantum-dash laser optical frequency comb
Aleksei I. Borodkin, Anton V. Kovalev, Massimo Giudici +4
Single-section quantum dash semiconductor lasers have attracted much attention as an integrated and simple platform for the generation of THz-wide and flat optical frequency combs…
Stimulated scattering in strongly coupled nanolasers induced by Rabi oscillations
Mathias Marconi, Julien Javaloyes, Fabrice Raineri +2
Two coupled-cavity systems, or "photonic dimers", are efficient test-beds for both fundamental optics -the realization of quantum correlated states, Josephson physics, and so forth…
Quench dynamics in strongly coupled laser cavities
Mathias Marconi, Julien Javaloyes, Philippe Hamel +5
Strongly coupled dissipative optical cavities with nonlinear interactions give new opportunities to explore symmetry breaking phenomena and phase transitions, Josephson dynamics an…
Mesoscopic limit cycles in coupled nanolasers
Mathias Marconi, Fabrice Raineri, Ariel Levenson +5
Two coupled semiconductor nanolasers exhibit a mode switching transition, theoretically characterized by limit cycle or mode-beating oscillations. Their decay rate is vanishi…
Identifying and anticipating the threshold bifurcation of a complex laser with permutation entropy
Juan Gancio, Cristina Masoller, Mathias Marconi
The permutation entropy (PE) is a statistical indicator that allows to quantify the complexity of a signal. Here we show that it is able to {identify and anticipate} the threshold…
Analysis of the phase-locking dynamics of a III-V-on-silicon frequency comb laser
Alexis Verschelde, Kasper Van Gasse, Bart Kuyken +3
We present the detailed characterization of the phase dynamics of a telecom hybrid III-V-on-silicon passively mode-locked laser with a ring cavity. We explore the various regimes o…
Direct observation of zero modes in a non-Hermitian nanocavity array
Flore Hentinger, Melissa Hedir, Bruno Garbin +5
Zero modes are symmetry protected ones whose energy eigenvalues have zero real parts. In Hermitian arrays, they arise as a consequence of the sublattice symmetry, implying that the…
Experimental study of speckle patterns generated by low-coherence semiconductor laser light
Donatus Halpaap, Mathias Marconi, Romain Hernandez +3
Speckle is a wave interference phenomenon that has been studied in various fields, including optics, hydrodynamics and acoustics. Speckle patterns contain spectral information of t…
