Optical communication technology has been advancing rapidly for several decades,
supporting our increasingly information-driven society and economy. Much of this progress …

Space-division multiplexing (SDM) uses multiplicity of space channels to increase capacity
for optical communication. It is applicable for optical communication in both free space and …

We summarize the latest advances in space-division multiplexing (SDM) for increasing the
capacity per fiber strand. We discuss SDM fibers, recent SDM transmission experiments …

To overcome the capacity crunch of optical communications based on the traditional single-
mode fiber (SMF), different modes in a few-mode fiber (FMF) can be employed for mode …

Space-division multiplexing has brought a fresh perspective to the optical fiber community
over the last three years and many global players around the world have been involved with …

We experimentally demonstrate an inline few-mode erbium doped fiber amplifier supporting
six spatial modes with reconfigurable differential gain control and excellent gain flatness …

We propose a planar lightwave circuit (PLC)-based mode multi/demultiplexer
(MUX/DEMUX) with an asymmetric parallel waveguide for mode division multiplexed (MDM) …

We experimentally demonstrate a few-mode erbium doped fiber amplifier (FM-EDFA)
supporting 6 spatial modes with a cladding pumped architecture. Average modal gains are …

An all-fiber few mode erbium doped fiber amplifier (FM-EDFA) with low differential modal
gain (DMG) is theoretically and experimentally demonstrated. Firstly, a double-cladding six …

Application of few-mode transmission (FMT) in transport optical network is currently under
scrutiny, especially for metro networks, where shorter distances and pressing traffic increase …
