Spatio-temporal extreme events in a laser with a saturable absorber
Cristina Rimoldi, Stéphane Barland, Franco Prati +1
We study extreme events occurring in the transverse section of the field emitted by a broad-area semiconductor laser with a saturable absorber. The spatio-temporal events o…
Refractory period of an excitable semiconductor laser with optical injection
Bruno Garbin, Axel Dolcemascolo, Franco Prati +3
Injection-locked semiconductor lasers can be brought to a neuron-like excitable regime when parameters are set close to the unlocking transition. Here we study experimentally the r…
Observation of electro-activated localized structures in broad area VCSELs
J. Parravicini, M. Brambilla, L. Columbo +5
We demonstrate experimentally the electro-activation of a localized optical structure in a coherently driven broad-area vertical-cavity surface-emitting laser (VCSEL) operated belo…
Reconfigurable photoinduced metamaterials in the microwave regime
Carlo Rizza, Alessandro Ciattoni, Francesco De Paulis +4
We investigate optically reconfigurable dielectric metamaterials at gigahertz frequencies. More precisely, we study the microwave response of a subwavelength grating optically impr…
A hybrid soliton-based system: generation and steering of cavity solitons by means of photorefractive soliton electro-activation
Lorenzo Columbo, Carlo Rizza, Massimo Brambilla +2
We propose a hybrid soliton-based system consisting of a centrosymmetric photorefractive crystal, supporting photorefractive solitons, coupled to a vertical cavity surface emitting…
