Phase distortions of attosecond pulses produced by resonance-enhanced high harmonic generation
New Journal of Physics, 2013 Resonant enhancement of high harmonic generation can be obtained in plasmas containing ions with strong radiative transitions resonant with harmonic orders. The mechanism for this enhancement is still debated.

PHOTON-PHOTON COLLISIONS [PDF]
Le Journal de Physique Colloques, 1982 Studies of photon-photon collisions are reviewed with particular emphasis on new results reported to this conference. These include results on light meson spectroscopy and deep inelastic eγ scattering. Considerable work has now been accumulated on resonance production by γγ collisions.

Single-photon microwave photonics
Science Bulletin, 2022 With the rapid development of microwave photonics technology, high-speed processing and ultra-weak signal detection capability have become the main bottlenecks in many applications. Thanks to the ultra-weak signal detection capability and the extremely low timing jitter properties of single-photon detectors, the combination of single-photon detection ...

Photonics for computing and computing for photonics [PDF]
Nanophotonics, 2020 The liaison between photonics and computing is a pillar of modern optics and subject of cutting-edge research for more than half a century. As in many scientific disciplines, high-performance computational methods have become essential for describing, designing, interpreting and ultimately predicting an optical system’s behaviour, and today the wide ...

Quantum entanglement of the spin and orbital angular momentum of photons using metamaterials
Science, 2018 Going quantum with metamaterials Metasurfaces should allow wafer-thin surfaces to replace bulk optical components. Two reports now demonstrate that metasurfaces can be extended into the quantum optical regime. Wang et al.
