A taper-fused side pump technique, which is based on the direct fusion-splicing of one or
several tapered pump fibers and a double-clad signal fiber, is a potential side pump …

Randomly-coupled multi-core fiber (MCF) technology has come to attract lots of attention
because of its strong applicability to long-haul transmission systems. Compared with weakly …

In this paper, we review space division multiplexing (SDM) transmission experimental
demonstrations and associated technologies. In past years, SDM achieved high capacity …

Abstract Space-division multiplexing (SDM), whereby multiple spatial channels in multimode
and multicore optical fibres are used to increase the total transmission capacity per fibre, is …

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 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 …

A cladding-pumped 4-core erbium-doped fiber (4C-EDF) with a pedestal structure has been
firstly, to the best of our knowledge, proposed and fabricated for space division multiplexing …

Passively Q-switched fiber lasers in the S-and C-band region were demonstrated using
molybdenum ditelluride (MoTe 2) as the saturable absorber (SA). The MoTe 2 was prepared …

Abstract Using PbSe quantum dots (QDs) as the gain medium doped in UV-gel, we
experimentally demonstrate a PbSe QDs doped fiber amplifier (QDFA) with ultra-bandwidth …

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