JAKE SALTZMAN, NEWS EDITOR [email protected]Researchers working as part of a multi-institution collaboration led by University of Arizona assistant professor Mohammed Hassan achieved what they said are previously unattainable data transfer speeds from an optical switching mechanism. The researchers exploited the reflectivity modulation of a fused silica dielectric system in a strong light field to demonstrate on/off-type optical switching with attosecond time resolution. At such switching speed, the work charts a course to deploy optical switches and light-based electronics at petahertz speeds, which are orders of magnitude...Read full articleRelated content from Photonics MediaArticlesModulator Drives Record-Fast Transmission in Face of Data TrafficAlthough silicon photonics holds potential as a platform for optical transceivers, owing largely to its CMOS compatibility, the approach is limited in its electro-optic bandwidth.
