摘要：
We propose, design and fabricate all-fiber broadband orbital angular momentum (OAM) generator and OAM 1 x 2 coupler in conventional graded-index multimode fiber, based on which OAM(+/- 1) and OAM(+/- 2) modes with high purity from 1480 nm to 1620nm are generated and OAM(+/- 1) modes are split into two branches over the C-band.
