Material-specific high-resolution table-top extreme ultraviolet microscopy
Wilhelm Eschen, Lars Loetgering, Vittoria Schuster +9
Microscopy with extreme ultraviolet (EUV) radiation holds promise for high-resolution imaging with excellent material contrast, due to the short wavelength and numerous element-spe…
Mid-Infrared Photon-Pair Generation in AgGaS
Mohit Kumar, Pawan Kumar, Andres Vega +3
We demonstrate non-degenerate photon-pair generation by spontaneous parametric down conversion in a silver gallium sulfide AgGaS crystal. By tuning the pump wavelength, we achi…
In-fiber second-harmonic generation with embedded two-dimensional materials
Gia Quyet Ngo, Emad Najafidehaghani, Ziyang Gan +10
Silica-based optical fibers are a workhorse of nonlinear optics. They have been used to demonstrate nonlinear phenomena such as solitons and self-phase modulation. Since the introd…
Metasurface-Assisted Quantum Ghost Discrimination of Polarization Objects
Andres Vega, Thomas Pertsch, Frank Setzpfandt +1
We develop a concept of metasurface-assisted ghost imaging for non-local discrimination between a set of polarization objects. The specially designed metasurfaces are incorporated…
Spontaneous Parametric Down-Conversion from Resonant Metasurfaces
Tomás Santiago-Cruz, Anna Fedotova, Vitaliy Sultanov +7
All-dielectric optical metasurfaces are a workhorse in nano-optics due to both their ability to manipulate light in different degrees of freedom and their excellent performance at…
