Understanding Task Performance of Time-Multiplexed Optical Reservoir Computing via Polynomial Expansion
Elias R. Koch, Julien Javaloyes, Svetlana V. Gurevich +1
We investigate the computational potential and limitations of a passive linear optical reservoir with a photodetector at the optical-to-electrical interface as the sole source of n…

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…
