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 …

Single-mode fiber's physical capacity boundaries will soon be reached; hence, alternative
solutions are much needed to overcome the multiplying and remarkably large bandwidth …

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 …

In recent years, space-division multiplexed (SDM) transmission in multimode and multicore
fiber structures has been attracting growing interest as a mean of scaling the capacity of the …

Optical fibers have often been considered to offer effectively infinite capacity to support the
rapid traffic growth essential to our information society. However, as demand has grown and …

We report record capacity data transmission at 305 Tb/s over 10.1 km, using space division
multiplexing (SDM) with 19 channels. To realize such a large SDM channel number, we …

A cladding pumped multicore erbium-doped fiber amplifier for simultaneous amplification of
6 channels is demonstrated. Peak gain over 32 dB has been obtained at a wavelength of …

Wavelength-division multiplexing (WDM) has been the workhorse of data networks,
accommodating exponential traffic growth for two decades. Recently, however, progress in …

Modal dispersion (MD) in a multimode fiber may be considered as a generalized form of
polarization mode dispersion (PMD) in single mode fibers. Using this analogy, we extend …
