We investigate optical transmission of an ultra-wideband signal in a standard single mode
fiber. Using a near continuous optical bandwidth exceeding 157 nm across the S-, C-and L …

Quantum key distribution (QKD) can offer communication with unconditional security and is
a promising technology to protect next generation communication systems. For QKD to see …

Mode‐division multiplexing (MDM) is attractive to enhance the link capacity of optical
interconnects by using multiple mode‐channels in multimode bus waveguides. As sharp …

We experimentally investigate high-capacity few-mode fiber transmission for short and
medium-haul optical links. In separate experiments, we demonstrate C+ L band …

Few-mode fibers and coupled-core multi-core fibers are attractive transmission media for
space-division multiplexed transmission systems as they enable a high spatial channel …

We investigate high-throughput, multi-band transmission in a 4-core multi-core fiber (MCF)
with the same 125 μm cladding diameter of standard single-mode fiber (SMF). A single …

We describe a series of optical transmission experiments based around single-mode, multi-
core fiber (MCF) amplified with 19-core, C+ L band erbium-doped fiber amplifier (EDFA) …

High-capacity, long-haul transmission over a coupled-core three-core multi-core fiber is
investigated in a recirculating loop experiment. We report key system characteristics, such …

We demonstrated simultaneous usage of 228 spatial channels (effectively) within a strand of
fiber. We fabricated a 13-km 39-core 3-mode fiber and constructed a bi-directional space …

We describe optical data transmission systems using homogeneous, single-mode, multi-
core fibers (MCFs). We first briefly discuss space-division multiplexing (SDM) fibers …
