In this video, I put my R/C EDF jet to the ultimate test—can it take off from water? Watch as I attempt this unique challenge, covering the setup, modifications, and flight results. Will it soar or ...

Abstract: A ring-core erbium-doped fiber (RC-EDF) with low differential modal gain (DMG) was fabricated by the Modified Chemical Vapor Deposition (MCVD). Based on the RC-EDF, the amplifier is ...

We propose and demonstrate an orbital angular momentum (OAM) fiber amplifier supporting 14 OAM modes based on a fabricated ring-core erbium-doped fiber (RC-EDF) with a tailored erbium-doped profile.
