Electrical control of single-photon emission in highly-charged individual colloidal quantum dots
Sergii Morozov, Evangelina L. Pensa, Ali Hossain Khan +6
Electron transfer to an individual quantum dot promotes the formation of charged excitons with enhanced recombination pathways and reduced lifetimes. Excitons with only one or two…
Objective-free excitation of quantum emitters with a laser-written micro parabolic mirror
Sergii Morozov, Stefano Vezzoli, Ali Hossain Khan +2
The efficient excitation of quantum sources such as quantum dots or single molecules requires high NA optics which is often a challenge in cryogenics, or in ultrafast optics. Here…
Broad frequency shift of parametric processes in Epsilon-Near-Zero time-varying media
Vincenzo Bruno, Stefano Vezzoli, Clayton DeVault +6
The ultrafast changes of material properties induced by short laser pulses can lead to frequency shift of reflected and transmitted radiation. Recent reports highlight how such a f…
Negative refraction in time-varying, strongly-coupled plasmonic antenna-ENZ systems
V. Bruno, C. DeVault, S. Vezzoli +14
Time-varying metasurfaces are emerging as a powerful instrument for the dynamical control of the electromagnetic properties of a propagating wave. Here we demonstrate an efficient…
Optical Analogue of the Dynamical Casimir Effect in a Dispersion-Oscillating Fibre
Stefano Vezzoli, Arnaud Mussot, Niclas Westerberg +6
The dynamical Casimir effect is the generation of pairs of real particles or photons from the vacuum as a result of a non-adiabatic change of a system parameter or boundary conditi…
Nanoscale design of the local density of optical states
Sandro Mignuzzi, Stefano Vezzoli, Simon A. R. Horsley +3
We propose a design concept for tailoring the local density of optical states (LDOS) in dielectric nanostructures, based on the phase distribution of the scattered optical fields i…
