New York: We won't, hopefully, have to fret over the slow data transmission soon.


A new laser developed by a research group at the California Institute of Technology (Caltech) holds the potential to increase the rate of data transmission in the optical-fibre network.

The optical-fibre is the backbone of the Internet.

“Light is capable of carrying vast amounts of information. But to utilise this potential, the laser light needs to be as spectrally pure (close to a single frequency) as possible,” explained post-doctoral scholar Christos Santis and graduate student Scott Steger who led the project.

The purer the tone, the more information it can carry.

Today's worldwide optical-fibre network is still powered by a laser known as the distributed-feedback semiconductor (S-DFB) laser, developed in the mid 1970s.
