Flat Magic Window
Felix Hufnagel, Alessio D'Errico, Hugo Larocque +3
Magic windows (or mirrors) consist of optical devices with a surface deformation or thickness distribution devised in such a way to form a desired image. The associated image inten…
High-speed imaging of spatiotemporal correlations in Hong-Ou-Mandel interference
Xiaoqin Gao, Yingwen Zhang, Alessio D'Errico +2
The Hong-Ou-Mandel interference effect lies at the heart of many emerging quantum technologies whose performance can be significantly enhanced with increasing numbers of entangled…
Linking topological features of the Hofstadter model to optical diffraction figures
Francesco Di Colandrea, Alessio D'Errico, Maria Maffei +6
In two, three and even four spatial dimensions, the transverse responses experienced by a charged particle on a lattice in a uniform magnetic field are fully controlled by topologi…
Full-mode Characterisation of Correlated Photon Pairs Generated in Spontaneous Downconversion
Alessio D'Errico, Felix Hufnagel, Filippo Miatto +2
Spontaneous parametric downconversion is the primary source to generate entangled photon pairs in quantum photonics laboratories. Depending on the experimental design, the generate…
Polychromatic Electric Field Knots
Manuel F. Ferrer-Garcia, Alessio D'Errico, Alicia Sit +2
The polarization of a monochromatic optical beam lies in a plane, and in general, is described by an ellipse, known as the polarization ellipse. The polarization ellipse in the tig…
