Time Crystals in Actively Mode-locked Lasers
Ruiling Weng, Elias R. Koch, Jesús Yelo-Sarrión +4
We report the first experimental observation of discrete time-crystal phases and crystallites in an actively mode-locked semiconductor laser. By tuning either the bias current or t…

Thermo-optical spiking and mixed-mode oscillations in injected Kerr microcavities
Elias R. Koch, Julien Javaloyes, Svetlana V. Gurevich
We investigate the nonlinear dynamics of vertically emitting Kerr microcavities under detuned optical injection, considering the impact of slow thermal effects. Our model integrate…

Pulse instabilities in harmonic active mode-locking: a time-delayed approach
Elias R. Koch, Svetlana V. Gurevich, Julien Javaloyes
We propose a time-delayed model for the study of active mode-locking that is valid for large values of the round-trip gain and losses. It allows us to access the typical regimes en…
