Magnetically Controlled Nanolasers Protect Optical Signals
ESPOO, Finland, Jan. 4, 2022 — A lasing control mechanism, introduced by a research team at Aalto University, enables users to control plasmonic nanolasers remotely, using a magnetic field. Until now, the only way to switch plasmonic nanolasers on and off has been through direct manipulation. The ability to control nanolasers with magnets supports more robust optical signaling through the emerging field of topological photonics, which aims to produce light signals that are immune to external disruptions.
