“…Using this correspondence, a lattice of spin-orbit states originally developed for neutrons has been implemented with photons. Optical lattices have led to studies of optical Talbot physics of structured orbital angular momentum (OAM) light beams [6,7], optical lattice structure shaping [8,9], and direct detection of optical spin-orbit states by the human eye [10,11]. By translating the physics of a periodic structure of spinorbit states further in photonics, we can take advantage of additional capabilities such as multi-particle entanglement.…”
