Technology is helping
communication companies merge telephone, television, and Internet
services, but
a push to deregulate may leave some customers on the wrong side of the
digital
divide during this convergence, according to a Penn State University
telecommunications
researcher.

Researchers
have developed a wireless link that bridges two fiber-optic points at
an unprecedented 20 billion bits of data per second. The phenomenal
speed, which is to be presented at the Optical Fiber Communication
Conference and Exposition in Los Angeles next week, was achieved using
much higher frequencies than have been typically used in mobile
communications.

Scientists at the University of Southampton, in collaboration with Penn State University have, for the first time, embedded the high level of performance normally associated with chip-based semiconductors into an optical fiber, creating high-speed optoelectronic function.

Sometimes total electrical isolation is a good thing—and that's the idea behind a power-over-fiber communications cable being developed by engineers at Sandia National Laboratories. The Sandia team is developing a hybrid cable design that uses fiber to send and regulate optical power to the communications electronics integral to the cable. A patent is pending on the design.

By
making nanoscale changes to the diameter of normal optical fiber,
engineers can create narrow sections that are able to confine light,
sending it on a back-and-forth on a corkscrew path. These
microresonators are not new, but researchers from OFS Laboratories in
Somerset, N.J., have developed a precise and efficient way to build long
chains of them, suggesting a way to make an optical computer.

Managing light to carry computer data is possible today with laser light beams that are guided along a fiber-optic cable. These waves consist of countless billions of photons, which carry information down the fiber across continents. A research team at the University of Alberta wants to refine the optical transmission of information by using a single photon.

Researchers from Cambridge University's Cavendish Laboratory have moved an individual electron along a wire, batting it back and forth over 60 times, rather like the ball in a game of ping-pong. The technique helps retain coherence, and could be beneficial in the development of quantum computing.

Australian researchers have
engineered one of the world's smallest ever nanowires for the next
generation
of telecommunication technology, bringing them one step closer to the
creation
of a 'photonic chip' which would lead to a faster, more sustainable
Internet.

Physicists at The City College of New York have found a new way to map spiraling light that could help harness untapped data channels in optical fibers. The new model, called a Higher Order Poincaré Sphere, could also advance quantum computing.

Because
illicit whisky costs huge sums in lost revenue and threatens brand
reputation, chemists have long been testing samples in the laboratory.
Now, researchers in Scotland are using an optical fiber innovation in
combination with infrared spectrometry to distinguish authentic and
counterfeit Scotch more quickly.
