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…
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…
