To speed up the writing and readout of magnetic information from storage devices, researchers are exploring the use of ultrashort laser pulses that can switch magnetic domains in solid-state materials. Although this route shows promise, the large number of magnetic materials interacting with one another, in a so-called quantum many-body system, has made this approach difficult to study. Exposing materials to intense laser pulses makes it possible to induce metal-insulator transitions, to control magnetic order and to generate transient superconducting behavior. However, pinning down the...Read full articleRelated content from Photonics MediaARTICLESPerfect Soliton Crystals Boost Performance of MicroresonatorsÉcole Polytechnique Fédérale de Lausanne (EPFL) scientists have bypassed light-bending losses that can occur when light pulses exit an optical microresonator, and have uncoupled...EuroPhotonics Winter 2019 IssueResearchers Customize Broadband Light Sources Using a Photonic Chip and AIResearchers from Institut National de la Recherche Scientifique (INRS) and the University of Sussex have collaborated to create an optical device that uses AI to control the properties of light....Photonics Spectra February 2019 IssueOptically Generated Tilted Pulses Can Be Directed Spatially and TemporallyPhysicists at the University of Konstanz have demonstrated the ability to spatially and temporally direct and control ultrashort electron pulses by using the light cycles of lasers.
