The United States has developed a 90 billion LED light emitting device

According to foreign media reports, researchers have recently developed a kind of LED light emitting device can be opened 90 billion times in one second, can be used as the basis of optical computing technology.

At present, there are as many as billions of transistors in the smart phone's battery, they use the power can be turned on or off billions of times per second to supply electricity. But if microchips can use photons instead of electrons to process and transmit data, the speed of the computer can be greatly improved. But first, researchers need to develop a light source that can be quickly turned on and off.

Although the laser can meet this requirement, but they are too high energy consumption and the problem of excessive size of the transmitter, so it is not suitable for working inside the computer. Now, the Duke University has developed this kind of fast light-emitting devices so that researchers from the production of light for the computer to use a step closer to the light source.

"This is the long-awaited goal in the field of science," United States assistant professor of electrical and computer engineering Duke University Maiken Mikkelse said, "we can according to the study to think about how to make fast switching equipment now, so the results of this study make us feel quite excited. "

"The research community for the use of LED to replace the laser for short distance optical communication has been of great interest, but these ideas have been limited by the slow fluorescent material emissivity, low efficiency and can not lead the photon reality," Mikkelse lab postdoctoral researcher Gleb Akselrod said, "now, we solve this problem in the distance a step.
