New Scroll Lasers Increase Data Rate
A new optical-based communication tool can transfer data as fast as a vortex. This optical advance, described in a study published in the journal Science, could be a core component of next-generation computers to meet the growing demand for information sharing in human society. It may also eliminate concerns about Moore's Law failure - Moore's Law says researchers will find new ways to continually make computers smaller, faster and cheaper.
For decades, high power laser pointer researchers have been working to integrate more components into silicon-based computer chips than ever before. Their success explains why today's smartphones have a higher computing power than the world's most powerful computers in the 1980s, and that time the cost of supercomputers is converted into today's currency, it will reach millions of dollars Of the giant, and its size and large file cabinet almost.
But the researchers are facing a bottleneck that the existing technology has been unable to meet the social needs of the data. Although the parties' forecasts are different, many people think it is likely to happen in the next five years. Researchers are solving this problem in a number of ways, including optical communication technology that uses light to transmit information. Examples of optical communication are very broad, from the old lighthouse to the modern use of television and Internet browsing fiber optic cable.
The 1000mw laser pointer is the core of today's optical communication system. Researchers have manipulated lasers in a variety of ways, the most common way is to bring together different signals into a single line to carry more information. But these techniques, especially wavelength division multiplexing and time division multiplexing, have already reached their limits.
The research team led by the University of Buffalo uses another light manipulation technique known as orbital angular momentum to drive advances in laser technology, which places the laser in a centrally eddy spiral pattern. Usually this kind of laser is still too big for the application on the current computer, but the team succeeded in reducing the turbulence to a degree comparable to the computer chip. As the laser beam propagates along a helical pattern, the information is encoded into a different vortex curve, so it can carry ten times more information than a conventional burning laser that travels in a straight line.
Scroll lasers are just one of the many components required to create more powerful computers and data centers, and ultimately require advanced transmitters and receivers to continue.
