DOI: 10.1016/j.ijleo.2021.166285

Abstract: Abstract Different designed Modal Gain Equalized Few Mode-Erbium Doped Fiber Amplifier (FM-EDFA) systems are evaluated and compared in this paper. These systems include Two Mode (2M-EDFA), Four Mode (4 M-EDFA) and Six Mode (6 M-EDFA).… read more here.

Published in 2020 at "Applied optics"

DOI: 10.1364/ao.404719

Abstract: We propose a technique for reducing the differential modal gain (DMG) that occurs in a two-mode erbium-doped fiber (2M-EDF) by inscribing voids in the core center of a 2M-EDF with a femtosecond laser. We show… read more here.

Published in 2019 at "Optics express"

DOI: 10.1364/oe.27.038087

Abstract: We theoretically propose two orbital angular momentum (OAM) erbium-doped ring-core fiber (RCF) amplifiers capable of providing relatively uniform gain for 22 modes with 18 OAM ones over the C-band. Two schemes of doping profile are… read more here.

Published in 2022 at "Optics letters"

DOI: 10.1364/ol.478350

Abstract: We characterize the differential modal group delay (DMGD) arising in few-mode fibers (FMFs) based on the digital re-sampling technique, which is commonly used in current digital signal processing flow at the receiver-side. When the DMGD… read more here.
