We demonstrate wavelength-and mode-division multiplexed transmission over a fiber re-
circulating loop comprising 50-km of low-DMGD few-mode fiber, and an optimized few-mode …

We numerically and experimentally demonstrated a low different modal gain (DMG) 5-LP
modes l-band fiber amplifier by using an extremely simple fiber structure. The effect of fiber …

A randomly coupled 12-core erbium-doped fiber amplifier (EDFA) operating in the C-or L-
band is investigated. We experimentally demonstrate that both C and L-band operation can …

We propose all-fiber mode multiplexer composed of two consecutive LP_11 mode selective
couplers that allows for the multiplexing of LP_01 mode and two-fold degenerate LP_11 …

We demonstrate a randomly coupled 12-core erbium-doped fiber (EDF) based cladding
pumped optical amplifier. In this paper, we show that a randomly coupled multicore EDF …

Featured Application Optical fiber transmission. Abstract Few-mode erbium-doped fiber
amplifiers (FM-EDFAs) are one of the most important optical subsystems for successful …

Cladding-pumped multicore erbium-doped fiber is an important element for future spatial
division multiplexing (SDM) amplification. We propose an M-type erbium-doped multicore …

We investigated the impact of varying the structural parameters, the bending and twisting
conditions on the mode-dependent gain (MDG) in a coupled-multi-core erbium-doped fiber …
