Random number generation from a self-chaotic broad-area VCSEL
Yohann G. Sanvert, Jules Mercadier, Stefan Bittner +1
The nonlinear dynamics of transverse and polarization modes of a broad-area vertical-cavity surface-emitting laser (BA-VCSEL) exhibit, without any external perturbation, chaos with…

Symmetry-Broken Cavity Solitons and Collective Polarization Conformity in Fabry-Perot Kerr Resonators
Yohann G. Sanvert, Abdullah Alabbadi, Lewis Hill +7
We report on the experimental generation of polarization symmetry-broken cavity solitons (CSs) in a passive, fiber-based, coherently-driven, Fabry-Perot (FP) Kerr resonator. Polari…

Polarization and tranverse mode nonlinear dynamics in a multimode VCSEL
Yohann G. Sanvert, Jules Mercadier, Stefan Bittner +2
We theoretically analyze the nonlinear dynamics and routes to chaos in a multimode vertical cavity surface-emitting laser (MM-VCSEL) in free-running operation. Including higher ord…
