Engineers at Caltech want to solve the problem of limited bandwidth of the optic fibers. The OFCs are replacing the copper wires to suit the ever growing needs of data communication. The latest achievement has enabled the researchers to focus light with nanometer precision - which might give more data carrying capacity to the fiber optic cables. The engineers have successfully built a 2 micron wide 'waveguide' - a tunnel that carries light with amorphous silicon dioxide (see the photo).


The technology may find several applications. The team believes that using this technology, hard disks will be able to hold more data using heat-assisted magnetic recording. While the current technology allows recording of about 1 TB of data per square inch, the new nano-focusing technology will boost it to 50 TB.
