Researchers show that subwavelength localization and line narrowing is possible in a very simple arrangement due to self-organization of Raman gas (molecular hydrogen) in a hollow photonic crystal fibre.
Scientists have been able to measure the ultrashort time delay in electron photoemission without using a clock. The discovery has important implications for fundamental research and cutting-edge technology.
Inspired by the hair of blue tarantulas, researchers made a structural-colored material that shows consistent color from all viewing directions. This finding overturns the conventional wisdom that long-range order photonic structures are always iridescent.
