Awesome…this may speed up the internet as well as improve other scientific applications!  (And it is just plain cool):

Researchers have been able to develop a light-emitting device that is able to turn on and off as many as 90 billion times per second. The device could be a way to greatly speed up data transmission in computers.

Things like smartphone batteries currently power transistors by flipping electronics on and off billions of times per second. However, if microchips were able to use photons instead of electrons, computers might be able to operate a lot faster.

To do this, however, engineers first had to create a light source that could be switched on and off extremely fast. While a laser might be able to do this, lasers are too power-hungry.

Let’s find out more and check out a video of how this works on page 2
