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…

Impact of phase modulation on the dynamics of temporal localized structures in injected Kerr microcavities

Marc Hunkemöller, Thomas G. Seidel, Julien Javaloyes +1

We theoretically investigate how phase modulation alters the dynamics of temporal localized structures (TLSs) in vertically emitting Kerr micro-cavities under detuned optical injec…

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…

Coherent pulse interactions in mode-locked semiconductor lasers

Thomas G. Seidel, Julien Javaloyes, Svetlana V. Gurevich

We study the dynamics of multipulse solutions in mode-locked lasers in presence of time-delayed feedback stemming, e.g., from reflections upon optical elements, and carrier dynamic…

Normal dispersion Kerr cavity solitons: beyond the mean field limit

T. G. Seidel, J. Javaloyes, S. V. Gurevich

We predict the existence of a novel type of temporal localized structure in injected Kerr--Gires--Tournois interferometers (KGTI). These bright pulses exist in the normal dispersio…

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…
