Celebrating the 20^ th anniversary of Optics Express, this paper reviews the evolution of
optical fiber communication systems, and through a look at the previous 20 years attempts to …

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 …

As the only method for all-weather, all-time and long-distance target detection and
recognition, radar has been intensively studied since it was invented, and is considered as …

Based on a variety of long-term network traffic data from different geographies and
applications, in addition to long-term scaling trends of key information and communication …

The Internet today transmits hundreds of terabits per second, consumes 9% of all electricity
worldwide and grows by 20–30% per year,. To support capacity demand, massively parallel …

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 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 …

Forthcoming capacity scaling requirements of optical networks and advances in optical fiber
communications beyond the omnipresent single-mode fiber operating over the conventional …

A compact two-mode (de) multiplexer (TM-MUX) based on Si nanowire for mode-division
multiplexing is designed. The TM-MUX is composed of two multimode interference (MMI) …
