A pair of photons enters an optical maze, and sometimes they leave as something new. Not new in the everyday sense, since ...
The rapid development of advanced optical technology has driven a strong demand for high-dimensional laser field manipulation, where the ability to tailor multiple degrees of freedom (DoFs) on-demand ...
Schematic of a single photon with zero angular momentum (green) splitting into two photons (red) with either zero or opposite angular momenta (sketched through the spatially varying color), which adds ...
