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 …

Lightwave communications is a necessity for the information age. Optical links provide
enormous bandwidth, and the optical fiber is the only medium that can meet the modern …

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 …

In optical communication systems, fibre nonlinearity is the major obstacle in increasing the
transmission capacity. Typically, digital signal processing techniques and hardware are …

Over the past few years, progress in hollow-core optical fiber technology has reduced the
attenuation of these fibers to levels comparable to those of all-solid silica-core single-mode …

Fiber nonlinearity is one of the major limitations to the achievable capacity in long distance
fiber optic transmission systems. Nonlinear impairments are determined by the signal …

Radio waves carry both energy and information simultaneously. Nevertheless, radio-
frequency (RF) transmissions of these quantities have traditionally been treated separately …

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 …

In the evolution of optical networks, spectral efficiency (SE) enhancement has been the most
cost-efficient and thus the main driver for capacity increase for decades. As a result, the …

The integration of high-speed optical communication and distributed sensing could bring
intelligent functionalities to ubiquitous optical fibre networks, such as urban structure …
