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 …

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 …

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 …

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

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 report simultaneous transmission of six spatial and polarization modes, each carrying 40
Gb/s quadrature-phase-shift-keyed channels over 96 km of a low-differential group delay …

We designed and fabricated a multi-core fiber (MCF) in which seven identical trench-
assisted pure-silica cores were arranged hexagonally. To design MCF, the relation among …

With wavelength-division multiplexing (WDM) rapidly nearing its scalability limits, space-
division multiplexing (SDM) seems the only option to further scale the capacity of optical …

We review different techniques for modulation of the electromagnetic properties of terahertz
(THz) waves. We discuss various approaches for electronic, optical, thermal and nonlinear …
