Orbital angular momentum (OAM) modes, an orthogonal complete basis for electromagnetic field distribution in optical fibers, offer a promising technology for independent spatial-domain transmission. Various ring fibers have emerged as leading candidates for supporting and manipulating OAM modes. Among these...

We propose and numerically demonstrate a conversion and multicasting scheme of orbital angular momentum (OAM) states by using N-core supermode fiber (NCSF), where the topological charges of converted OAM states mainly depend on the injected OAM state and the number of fiber cores. The conversion...
Orbital angular momentum mode multiplexed transmission in heterogeneous few-mode and multi-mode fiber network Mode-division multiplexing (MDM), which employs the spatial modes of light as information carriers, has been widely investigated to increase the transmission capacity. Few-mode fibers (FMFs) an...
Spatial division multiplexed optical transmission over a multi-ring-core orbital angular momentum (OAM) fibre is reported for the first time. The seven cores in the fibre each supports OAM modes belonging to mode groups (MGs) of topological charge | l |
Acousto-optic interaction in optical fiber is examined from the perspective of copropagating optical and acoustic vortex modes. Calculation of the acousto-optic coupling coefficient between different optical modes leads to independent conservation of spin and orbital angular momentum of the interacting photo...
