Spatiotemporal Metasurface for Ultrafast All-Optical Wavefront Shaping
Mert Akturk, Giulia Crotti, Andrea Schirato +6
Optical metasurfaces have established themselves as exceptional nanophotonic platforms to control the properties of light at subwavelength scales. By properly designing the geometr…
Strong light-matter interactions in hybrid polaritonic systems
Ben Johns, Andrea Schirato, Federico Toffoletti +13
Strong light-matter coupling gives rise to polaritons - hybrid excitations whose mixed photonic and matter character enables control over optical, electronic and chemical propertie…
Broadband ultrafast self-heterodyned chiro-optical spectroscopy
Francesco Gucciâ, Andrea Iudicaâ, Andres Valladares Y Tacchiâ +12
Ultrafast chiro-optical spectroscopy provides unique access to the structural dynamics of molecules, spin-valley relaxation in semiconductors, and the non-equilibrium optical respo…
Layered Bimetal Nanoporous Platforms for SERS Sensing
Yanqiu Zou, Anastasiia Sapunova, Tommaso Giovannini +15
Nanoporous metals are extensively investigated as platforms for applications in plasmonics. They present high surface areas and strong local electric fields that can be tuned at di…
Comparison of near-field light intensities: plasmon nanofocusing vs localized plasmon resonance
Tongyao Li, Andrea Schirato, Taku Suwabe +3
The localized surface plasmon resonance of metallic nanostructures produces strongly localized and enhanced near-field light, significantly contributing to nanophotonics research a…
Electron-Phonon Temperature Inversion in Nanostructures under Pulsed Photoexcitation
Qian Ye, Stephen K. Sanders, Andrea Schirato +1
Photoexcitation of metallic nanostructures with short optical pulses can drive non-thermal electronic states, which, upon decay, lead to elevated electronic temperatures ($T_e \gtr…
