Disentangling Memory and Nonlinearity in Time-Multiplexed Optical Reservoir Computing
Elias R. Koch, Julien Javaloyes, Svetlana V. Gurevich +1
We analyze and disentangle the individual and combined roles of nonlinearity, transient dynamics, and delayed feedback, and investigate how these mechanisms contribute to different…

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…
