In order to overcome the capacity limitations of current lightwave systems based on the
single-mode optical fiber, massively parallel transmission in the spatial domain [space …

Research on space-division multiplexing (SDM) came to prominence in early 2010 being
primarily proposed as a means of multiplying the information-carrying capacity of optical …

Data rates in optical fiber networks have increased exponentially over the past decades and
core-networks are expected to operate in the peta-bit-per-second regime by 2030. As …

Multicore fibers (MCFs) are expected as a good candidate for overcoming the capacity limit
of a current optical communication system. This paper describes the recent progress on the …

We observe efficient supercontinuum generation that extends into the visible spectral range
by pumping a low differential mode group delay graded index multimode fiber in the normal …

Mode-division multiplexing (MDM) using few-mode fibers (FMFs) appears as a promising
technology to increase fiber capacity by a few orders of magnitude and sustain the traffic …

Multicore fibers and few-mode fibers have potential application in realizing dense-space-
division multiplexing systems. However, there are some tradeoff requirements for designing …

We present a new technique allowing the fabrication of large modal count photonic lanterns
for space-division multiplexing applications. We demonstrate mode-selective photonic …

50-μm-diameter graded-index core multimode fibers can be adapted to mode-division-
multiplexed transmissions that use multiple-input-multiple-output digital signal processing …

We describe the design and characterization of a heterogeneous 36-core, three-mode fiber
with three core types. Intercore crosstalk for LP_11 modes is estimated to be below− 31 dB …
