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…
Adiabatic frequency shifting in epsilon near zero materials: The role of group velocity
Jacob B Khurgin, Matteo Clerici, Vincenzo Bruno +9
We investigate adiabatic frequency conversion using epsilon near zero (ENZ) materials and show that while the maximum frequency conversion for a given change of permittivity does n…
Two-photon Quantum Interference and Entanglement at 2 μm
Shashi Prabhakar, Taylor Shields, Adetunmise Dada +12
Quantum-enhanced optical systems operating within the 2- to 2.5-m spectral region have the potential to revolutionize emerging applications in communications, sensing, and metro…
