The only thing standing in the way is some creative materials
science, and researchers at the Georgia Institute of Technology may
have just found the key to converting everything from individual
computers to data networks into blazing-fast, all-optical transmission devices.
The problem with current telecommunications speeds is that no matter
how fast we beam information around the globe, time is lost while
photonic signals are converted into electronic signals and vice versa.
But with the right materials, low-power high-speed all-optical signal
processing is possible, cutting out that intermediary step. We just
haven't arrived at the right materials to get the job done in a
