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…
Nonequilibrium dynamics of high energy transitions in monolayer WSe
Oleg Dogadov, Jorge Cervantes-Villanueva, Nicholas Olsen +6
High-energy optical transitions in monolayer transition-metal dichalcogenides exhibit characteristics that are markedly distinct from those of lower-lying band-edge excitons. These…
Excitonic Mott transition without population inversion
Oleg Dogadov, Armando Genco, Allison R. Cadore +12
Exciton dissociation via the excitonic Mott transition (EMT) governs the high-density optical response of semiconductors and sets fundamental limits for optoelectronic devices. The…
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…
Ultrafast valleytronic logic operations
Francesco Gucci, Eduardo B. Molinero, Mattia Russo +8
Information processing currently reaches speeds as high as 800 GHz. However, the underlying transistor technology is quickly approaching its fundamental limits and further progress…
Visualizing hot carrier dynamics by nonlinear optical microscopy at the atomic length scale
Yang Luo, Shaoxiang Sheng, Andrea Schirato +5
Probing and manipulating the spatiotemporal dynamics of hot carriers in nanoscale metals is crucial to a plethora of applications ranging from nonlinear nanophotonics to single mol…
