文摘In 1992,Professor Allen’s paper published in Physical Review A indi-cated that laser light with a Laguerre-Gaussian amplitude distribution has an orbital angular momentum(OAM).Since then,conceptual stud-ies on OAM of photons have been attracting continual attention in physics and optics communities.In recent years,we have witnessed the birth and fast development of many break-through technologies driven by the concept of OAM,from advanced light-field manipulation to super-resolution imaging,classical and quantum optical communi-cations,and many others.
