Optical fibers provide an excellent platform for transmitting light over long distances, manipulating it and enhancing light-matter interaction. Now, the "Ultrafast & Twisted Photonics" research group at the Max Planck Institute for the Science of Light (MPL) has developed a new hollow-core fiber that selectively guides optical vortices depending on their helicity and has potential applications in chiral sensing, vortex mode generation, and optical communications.
