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…
Harnessing quadratic optical response of two-dimensional materials through active microcavities
Alessandro Ciattoni, Carlo Rizza
We propose a method for efficiently harnessing the quadratic optical response of two-dimensional graphene-like materials by theoretically investigating second harmonic generation f…
Space-time coupling in the up-conversion of broadband down-converted light
Enrico Brambilla, Ottavia Jedrkiewicz, Paolo di Trapani +1
We investigate the up-conversion process of broadband light from parametric down-conversion (PDC), focusing on the spatio-temporal spectral properties of the sum-frequency generate…
On the nature of spatiotemporal light bullets in bulk Kerr media
D. Majus, G. Tamošauskas, I. Gražulevičiūtė +5
We present a detailed experimental investigation, which uncovers the nature of light bullets generated from self-focusing in a bulk dielectric medium with Kerr nonlinearity in the…
Graphene nonlinearity unleashing at lasing threshold in graphene-assisted cavities
Alessandro Ciattoni, Carlo Rizza
We investigate the nonlinear optical features of a graphene sheet embedded in an active cavity and we show that, when tuned near its lasing threshold, the cavity is able to isolate…
