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…

Synchronization of complex spatio-temporal dynamics with lasers
Jules Mercadier, Stefan Bittner, Marc Sciamanna
Synchronization is the spontaneous alignment of the dynamics of weakly-coupled oscillators. In addition to temporal dynamics like periodic and chaotic oscillations, also the spatio…

Chaos from a free-running broad-area VCSEL
Jules Mercadier, Stefan Bittner, Damien Rontani +1
We experimentally report on the detection of chaos from a free-running commercial broad-area VCSEL without the need for external perturbation such as optical feedback, injection or…
