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…
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…
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…
Influence of optical feedback on harmonic pulsating solutions of long-cavity mode-locked VECSELs
A. Bartolo, T. Seidel, N. Vigne +8
We analyse the effect of optical feedback on the dynamics of external-cavity mode-locked semiconductor lasers operated in the long cavity regime. Depending on the ratio between the…
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…
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…
