The Performance of Orbital Angular Momentum Mode (|<i>l</i>| = 1~3) Amplification Based on Ring-Core Erbium-Doped Fibers

The Performance of Orbital Angular Momentum Mode (|<i>l</i>| = 1~3) Amplification Based on Ring-Core Erbium-Doped Fibers

We demonstrated that a ring-core erbium-doped fiber amplifier (RC-EDFA) can support orbital angular momentum (OAM) modes with topological charges (|<i>l</i>| = 1~3). The dependence of the characteristics on the length of the RC-EDF was investigated experimentally, including an investigat...
