Generation of Tunable Entanglement from Thin-Film Lithium Niobate
Saniya Shinde, Maximilian A. Weissflog, Shaun Lung +7
Entangled photon pairs play a major role in various modern technologies such as quantum imaging, communication, and computing. Conventional photon-pair sources are often based on s…
Enhanced photon-pair generation from a van der Waals metasurface
Tongmiao Fan, Yilin Tang, Shaun Lung +11
Quantum photon pairs play a pivotal role in many quantum applications. Metasurfaces, two-dimensional arrays of nanostructures, have been studied intensively to enhance and control…
Directionally Tunable Co- and Counter-Propagating Photon Pairs from a Nonlinear Metasurface
Maximilian A. Weissflog, Jinyong Ma, Jihua Zhang +6
Nonlinear metasurfaces have recently been established as a new platform for generating photon pairs via spontaneous parametric down-conversion. While for classical harmonic generat…
Entangled Photon-pair Generation in Nonlinear Thin-films
Elkin A. Santos, Maximilian A. Weissflog, Thomas Pertsch +2
We develop a fully vectorial and non-paraxial formalism to describe spontaneous parametric down-conversion in nonlinear thin films. The formalism is capable of treating slabs with…
A Tunable Transition Metal Dichalcogenide Entangled Photon-Pair Source
Maximilian A. Weissflog, Anna Fedotova, Yilin Tang +16
Entangled photon-pair sources are at the core of quantum applications like quantum key distribution, sensing, and imaging. Operation in space-limited and adverse environments such…
Nonlinear Nanoresonators for Bell State Generation
Maximilian A. Weissflog, Romain Dezert, Vincent Vinel +6
Entangled photon states are a fundamental resource for optical quantum technologies and investigating the fundamental predictions of quantum mechanics. Up to now such states are ma…
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…
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…
Spontaneous photon-pair generation at the nanoscale
Giuseppe Marino, Alexander S. Solntsev, Lei Xu +13
Optical nanoantennas have shown a great capacity for efficient extraction of photons from the near to the far-field, enabling directional emission from nanoscale single-photon sour…
