A nanolaser for fast and efficient data processing with light from TU München

As reported by TU Munich in EurekAlert!: Physicists at the Technical University of Munich (TUM) have developed a nanolaser, a thousand times thinner than a human hair. Thanks to an ingenious process, the nanowire lasers grow right on a silicon chip, making it possible to produce high-performance photonic components cost-effectively. This will pave the way for fast and efficient data processing with light in the future.
 

"Today already, transistors are merely a few nanometers in size. Further reductions are horrendously expensive," says Professor Jonathan Finley, Director of the Walter Schottky Institute at TUM. "Improving performance is achievable only by replacing electrons with photons, i.e. particles of light."
