Topological states of light and darkness: static, dynamic, and spatiotemporal vortices by Dr. Chen-Ting Liao
In this talk, Dr. Chen-Ting Liao introduced the topology of light – the light carrying orbital angular momentum (OAM). The OAM of light can be static, dynamic, or spatiotemporal. Static OAM of light has been known for three decades and has found numerous applications, from optical trapping, and...
