demonstrate generation of OAM beam through the well-known fused fiber coupler
fabricated using single mode fiber (SMF) and OAM air-core fiber [10, 11], by using the

Abstract
We demonstrate the orbital angular momentum (OAM) beam generation using an all-fiber fused coupler based on single mode fiber (SMF) and air-core fiber. The fabricated device is directly SMF compatible with~ 80% power coupling efficiency.
