Quantum-enhanced second harmonic generation beyond the photon pairs regime
Thomas Dickinson, Ivi Afxenti, Giedre Astrauskaite +8
Two-photon processes are crucial in applications like microscopy and microfabrication, but their low cross-section requires intense illumination and limits, e.g., the penetration d…
Polarization Purity and Dispersion Characteristics of Nested Antiresonant Nodeless Hollow-Core Optical Fiber at Near- and Short-wave-IR Wavelengths for Quantum Communications
Ivi Afxenti, Lijun Yu, Taylor Shields +5
Advancements in quantum communication and sensing require improved optical transmission that ensures excellent state purity and reduced losses. While free-space optical communicati…
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…
Superradiant Amplification of Acoustic Beams via Medium Rotation
Daniele Faccio, Ewan M. Wright
Superradiant gain is the process in which waves are amplified via their interaction with a rotating body, examples including evaporation of a spinning black hole and electromagneti…
Extreme Events in Resonant Radiation from Three-dimensional Light Bullets
Thomas Roger, Donatas Majus, Gintaras Tamosauskas +5
We report measurements that show extreme events in the statistics of resonant radiation emitted from spatiotemporal light bullets. We trace the origin of these extreme events back…
On the nature of spatiotemporal light bullets in bulk Kerr media
D. Majus, G. Tamošauskas, I. Gražulevičiūtė +5
We present a detailed experimental investigation, which uncovers the nature of light bullets generated from self-focusing in a bulk dielectric medium with Kerr nonlinearity in the…
Spatiotemporal Amplitude and Phase Retrieval of Bessel-X pulses using a Hartmann-Shack Sensor
Fabio Bonaretti, Daniele Faccio, Matteo Clerici +2
We propose a new experimental technique, which allows for a complete characterization of ultrashort optical pulses both in space and in time. Combining the well-known Frequency-Res…
