Duke University researchers to develop ultra-fast LED open and close 90 billion times within 1 second
According to foreign media reports, some researchers recently developed an LED light-emitting device that can turn on and off 90 billion times in one second, which can be used as the basis for optical computing technology. Currently, smartphones have as many billions of transistors inside their batteries, powered by billions of open and closed electrons per second. But if microchips can use photons instead of electrons to process and transmit data, the speed of the computer can be dramatically increased. But first, researchers need to develop light sources that can be quickly switched on and off. Although lasers meet this requirement, they have the problems of excessive energy consumption and oversized launcher, making them unsuitable for operation inside a computer. Now, the rapid luminescence device developed by Duke has taken researchers one step closer to making a light source suitable for use in a light computer. "This is the long-awaited goal in science," said Maiken Mikkelse, an assistant professor of electrical and computer engineering at Duke University in the United States. "We can now think of how to make a fast-switching device based on this research, so this research brings us Feel quite excited. " "There has been a great deal of interest in the use of LED-based lasers for short-range optical communication in the research community, but these ideas have always been limited by the slow emissivity of fluorescent materials, lower energy efficiency, and the inability to direct photons," said Mikkelse Laboratories Gleb Akselrod, a postdoctoral fellow, said: "Now we are one step closer to solving the problem."
