Tunable broadband light emission from graphene
Lavinia Ghirardini, Eva A. A. Pogna, Giancarlo Soavi +12
Graphene is an ideal material for integrated nonlinear optics thanks to its strong light-matter interaction and large nonlinear optical susceptibility. Graphene has been used in op…
Enhanced nonlinear optical response of single metal-dielectric nanocavities resonating in the near-infrared
Nicolò Maccaferri, Attilio Zilli, Tommi Isoniemi +5
Harmonic generation mechanisms are of great interest in nanoscience and nanotechnology, since they allow generating visible light by using near-infrared radiation, which is particu…
Evidence for cascaded third harmonic generation in non-centrosymmetric gold nanoantennas
Michele Celebrano, Andrea Locatelli, Lavinia Ghirardini +10
The optimization of nonlinear optical processes at the nanoscale is a crucial step for the development of nanoscale photon sources for quantum-optical networks. The development of…
Plasmon-enhanced second harmonic sensing
Lavinia Ghirardini, Anne-Laure Baudrion, Marco Monticelli +7
It has been recently suggested that the nonlinear optical processes in plasmonic nanoantennas allow for a substantial boost in the sensitivity of plasmonic sensing platforms. Here…
Room-temperature 1.54 m photoluminescence of Er:O centers at extremely low concentration in silicon
Michele Celebrano, Lavinia Ghirardini, Paolo Biagioni +11
The demand for single photon sources at m, which follows from the consistent development of quantum networks based on commercial optical fibers, makes Er:O centers…
Non-local opto-electrical spin injection and detection in germanium at room temperature
Fabien Rortais, Carlo Zucchetti, Lavinia Ghirardini +13
Non-local carrier injection/detection schemes lie at the very foundation of information manipulation in integrated systems. This paradigm consists in controlling with an external s…
Monolithic AlGaAs second-harmonic nanoantennas
V. F. Gili, L. Carletti, A. Locatelli +9
We demonstrate monolithic aluminum gallium arsenide (AlGaAs) optical anoantennas. Using a selective oxidation technique, we fabricate such epitaxial semiconductor nanoparticles on…
