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

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 …

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 …

Single-mode fibres with low loss and a large transmission bandwidth are a key enabler for
long-haul high-speed optical communication and form the backbone of our information …

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 …

The optical fibre is an essential tool for our communication infrastructure since it is the main
transmission channel for optical communications. The latest major advance in optical fibre …

The optical switches for single-mode operation cannot be directly utilized in optical
communication and interconnect systems adopting mode-division multiplexing. In this paper …

We present a compact (130 μm cladding diameter) trench-assisted multi-orbital-angular-
momentum (OAM) multi-ring fiber with 19 rings each supporting 22 modes with 18 OAM …

A compact low-crosstalk multi-ring fiber transmitting multiple orbital angular momentum
(OAM) modes is presented. The multi-OAM-mode multi-ring fiber (MOMRF) consists of 7 …

We report a two-span, 67-km space-division-multiplexed (SDM) wavelength-division-
multiplexed (WDM) system incorporating the first reconfigurable optical add–drop …
