Realization of room temperature polaritonic vortex in momentum space with hybrid Perovskite metasurface

Nguyen Ha My Dang, Simone Zanotti, Céline Chevalier +9

Exciton-polaritons are mixed light-matter excitations that result from the strong coupling regime between an active excitonic material and photonic resonances. Harnessing these hyb…

Theoretical and practical aspects of the design and production of synthetic holograms for transmission electron microscopy

Paolo Rosi, Federico Venturi, Giacomo Medici +10

Beam shaping - the ability to engineer the phase and the amplitude of massive and massless particles - has long interested scientists working on communication, imaging and the foun…

Tailoring of Plasmonic Functionalized Metastructures to Enhance Local Heating Release

Antonio Ferraro, Giuseppe Emanuele Lio, Abdelhamid Hmina +3

Plasmonic nanoheaters are reported that produce a significant local heating when excited by a 532 nm wavelength focussed laser beam. A significant temperature increase derives from…

Polariton Bose-Einstein condensate from a Bound State in the Continuum

V. Ardizzone, F. Riminucci, S. Zanotti +13

Optical bound states in the continuum (BIC) are peculiar topological states that, when realized in a planar photonic crystal lattice, are symmetry-protected from radiating in the f…

Transparent Conductive Oxides-based Architectures for the Electrical Modulation of the Optical Response: A Spectroscopic Ellipsometry Study

Maria Sygletou, Francesco Bisio, Stefania Benedetti +4

Transparent Conductive Oxides (TCOs) are a class of materials that combine high optical transparency with high electrical conductivity. This property makes them uniquely appealing…

Homogeneous quantum cascade lasers operating as Terahertz frequency combs over their entire operational regime

Alessandra Di Gaspare, Leonardo Viti, Harvey E. Beere +2

We report a homogeneous quantum cascade laser (QCL) emitting at Terahertz (THz) frequencies, with a total spectral emission of about 0.6 THz centered around 3.3 THz, a current dens…
