• Compact amplifier might revolutionise optical communication

    The novel compact optical amplifier is hundreds of instances smaller than its precursor. Credit score: Ping Zhao, Zhichao Ye and Yen Strandqvist/Chalmers College of Expertise Researchers at Chalmers College of Expertise, Sweden, current a singular optical amplifier that’s anticipated to revolutionize each area and fiber communication. The brand new amplifier presents excessive efficiency, is compact sufficient to combine right into a chip simply millimeters in measurement, and—crucially—doesn’t generate extra noise. “This could possibly be in comparison with switching from older, dial-up web to trendy broadband, with excessive pace and high quality,” says Professor Peter Andrekson, Head of the Photonics Laboratory on the Division of Microtechnology and Nanoscience at Chalmers.
