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.
