Terahertz Bandwidth Could Make Cellphones 1,000 Times Faster

Forget 3G and 4G. In fact, forget about the gigahertz frequency altogether—a team of researchers at the University of Pittsburgh say they've managed to devise a means of transmitting data thousands of times faster.

The team led by Hrvoje Petek, a physics and chemistry professor in Pitt's Kenneth P. Dietrich School of Arts and Sciences, successfully created what they call a "frequency comb" that "spans more than 100 terahertz (THz) of bandwidth by exciting a coherent collective of atomic motions in a semiconductor silicon crystal."

The frequency comb is created by the division of "a single color of light into a series of evenly spaced spectral lines for a variety of uses."

What that means is that Petek and his colleagues have devised a structure that could theoretically transmit data to devices like cellphones and computers in the terahertz frequency region—and in fact observed reflected light oscillating at 15.6 THz during their experiments.
