Ultrafast light switch for optical data components

By pairing a nanostructure of silver with an atomically thin semiconductor layer, a team of researchers from Italy, the U.K., and Germany, led by Christoph Lienau, a physics professor at the University of Oldenburg, created an ultrafast switching mirror device that can serve as an optical transistor—and it clocks in at a speed 10,000x faster […]

Nonlinear metasurfaces convert infrared light to visible

The injected pump field-generates third-harmonic radiation within the visible (close to 500 nm) inside the silicon, which inherits the pump’s phase gradient. This gives rise to nonlinear polarization currents that scatter the third harmonic to the far field in a direction dictated by the engineered phase gradient. Because the phase gradient of the third-harmonic field

Near-range LiDAR may monitor, warn Arctic ships about dangerous icing

The Marine Icing model for the Norwegian Coast Guard (NoCG; MINCOG) formulated in 2016 by Eirik Samuelsen of the Norwegian Meteorology Institute includes more metocean data, plus selected ship and course details based on the accretion rates observed onboard three Norwegian Coast Guard vessels of the class NoCG “Nordkapp” navigating within the Barents Sea during the
