Optical networks are facing fundamental capacity scalability problems owing to Shannon
limits in silica fiber, frequently summarized as the “optical networks capacity crunch.” We …

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 …

Researchers are within a factor of 2 or so from realizing the maximum practical transmission
capacity of conventional single-mode fibre transmission technology. It is therefore timely to …

Since the first deployments of fiber-optic communication systems three decades ago, the
capacity carried by a single-mode optical fiber has increased by a staggering 10 000 times …

In 2010, the scientific and engineering communities cel-ebrated the 50th anniversary of the
first demonstration of the laser, the 40th anniversary of the first demonstration of a low-loss …

Demands by the communications industry for greater and greater bandwidth push the
capability of conventional wireless technology. Part of the Radio Spectrum that is suitable for …
