High-resolution dynamic consistency analysis of photonic time-delay reservoir computer
Lucas Oliverio, Damien Rontani, Marc Sciamanna
We numerically investigate a time-delayed reservoir computer architecture based on a single mode laser diode with optical injection and optical feedback. Through a high-resolution…
Complex nonlinear dynamics of polarization and transverse modes in a broad-area VCSEL
Stefan Bittner, Marc Sciamanna
Lasers can exhibit nonlinear and chaotic dynamics driven by the interaction of multiple lasing modes, and investigating the different scenarios of mode competition and bifurcations…
Pattern generation and symbolic dynamics in a nanocontact vortex oscillator
Myoung-Woo Yoo, Damien Rontani, Jérémy Létang +6
Harnessing chaos or intrinsic nonlinear behaviours from dynamical systems is a promising avenue for the development of unconventional information processing technologies. However,…
Chaos in Magnetic Nanocontact Vortex Oscillators
Thibaut Devolder, Damien Rontani, Sébastien Petit-Watelot +10
We present an experimental study of spin-torque driven vortex self-oscillations in magnetic nanocontacts. We find that above a certain threshold in applied currents, the vortex gyr…
Chaotic dynamics in a macrospin spin-torque nano-oscillator with delayed feedback
Jérôme Williame, Artur Difini Accioly, Damien Rontani +2
A theoretical study of delayed feedback in spin-torque nano-oscillators is presented. A macrospin geometry is considered, where self-sustained oscillations are made possible by spi…
Deterministic polarization chaos from a laser diode
Martin Virte, Krassimir Panajotov, Hugo Thienpont +1
Fifty years after the invention of the laser diode and fourty years after the report of the butterfly effect - i.e. the unpredictability of deterministic chaos, it is said that a l…
