Much like carbon nanotubes
and quantum computing
, terahertz technologies have been promising
miracles for nearly as long as humans have been able to distinguish water from fire. We exaggerate, but barely
. A crafty team assembled at the University of Pittsburgh seems to have no qualms with moving forward, however, recently announcing a new physical basis for terahertz bandwidth. Those involved managed to have success in generating a frequency comb -- "dividing a single color of light into a series of evenly spaced spectral lines for a variety of uses -- that spans a more than 100 terahertz bandwidth by exciting a coherent collective of atomic motions in a semiconductor silicon crystal." For those who managed to make it through the technobabble, we're told that the ability to modulate light with such a bandwidth could "increase the amount of information carried by more than 1,000 times when compared to the volume carried with today's technologies." Smartphones, computers and even airline check-in kiosks that operate 1,000 faster than they do today? Sure, we'll take that. But, how about give us a ring when Wally World deems it ripe for commercialization? We'll be waiting -- pinky promise.
