Seven-Ring-Core Erbium-Doped Fiber for OAM-MDM Amplification

IEEE Photonics Journal, 2023
Orbital angular momentum (OAM) mode division multiplexing (MDM) amplification in a seven-ring-core erbium-doped fiber (7-RC-EDF) has been experimentally demonstrated, in which the 1st–4th order OAM modes within each core of the 7-RC-EDF can be ...
