• Russian Scientists Develop New Metasurfaces for Deep UV-Imaging

  Russian researchers developed a new material, which converts infrared light to ultrashort pulses of ultraviolet. For this purpose, the scientists exposed silicon film to laser so that its relief adjusted under light wavelength and made properties of the material resonant. In the end, the researchers got a cheap and easy-to-make metasurface, which is as effective as existing ones. The new technology can help create compact UV generators for biophotonics and medicine, and also devices for ultradense data processing in optical communication. The study was published in Nanoscale.

• Nonlinear Metamaterials in Making Computers More Effective

  As of now, optical systems for information processing are a trend developed by scientists worldwide, as they can greatly enhance computations. Many put their hopes in the use of nonlinear metamaterials. The first step to it is increasing the efficiency of nonlinear signal conversion. Maxim Gorlach from ITMO's Nano-photonics and Metamaterials Center and his colleagues work on solving one of the fundamental problems that contribute to the research of nonlinear metamaterials' properties with regard to spatial dispersion. Their results were highly appreciated by international experts at the Metamaterials-2016 international conference in Crete — the team was awarded a diploma for the best theoretical research.
