• Discovered Ultrafast Optical Effects in Metasurfaces Bring Scientists Closer to Next-Gen Devices for High-Speed Information Processing

  Working on a project of the Russian Science Foundation, ITMO scientists together with their colleagues from China, Australia, the US, and France have delivered experimental proof that dielectric silicon metasurfaces can rapidly change their optical properties under the influence of short light pulses. The discovered effect offers new prospects for cutting-edge computing devices.

• ITMO Physicists Found New Way to Optimize Nanoparticles and Light Interaction

  ITMO scientists have been the first to describe new features of dielectric nanoparticles’ optical response using an improved method for electromagnetic field analysis that can take into account more complex configurations of bias currents inside the objects. These effects allow to better understand the processes in nanoparticles and adjust their behavior for more efficient light control in devices such as nanolasers or sensors. The results have been published in Laser and Photonics Reviews and selected as materials for the issue cover.

• ITMO’s Topological Insulators Research Among 2017’s Top Achievements in Photonics

  Optics & Photonics News journal has recognised a recent study on three-dimensional topological insulators as one of the year’s most promising advances in photonics. These structures are capable of controlling light without any losses caused by absorption and defects of material, showing great potential for application in communication networks, antennas and optical computers.

• Cameras On A Chip And Holographic Displays: How Dielectric Nanophotonics Changes Our Future

  Tunable flat optics which can help create ultra-thin lenses with variable focal length and even create a camera on a chip, or smartphone displays that do not show 2D images, but 3D holograms - these are not some concepts from a recent sci-fi movie, but real projects that can soon be completed thanks to development of dielectric nanophotonics. Nowadays, research on this subject is conducted in many of the world's leading universities and science centers, and in March 2017, Arseniy Kuznetsov from the A-STAR's Data Storage Institute (DSI) in Singapore got the prestigious THE IET AF Harvey Prize for research on dielectric nanoantennas and their application in development of new high-technology devices. Since 2011, ITMO University also works on research in this field in collaboration with Mr. Kuznetsov. Read about what opportunities this research offers and how sci-fi translates into reality in our article.
