• ITMO Scientists Create World’s Smallest Silicon Light Source

  Researchers at ITMO University have developed a new photoluminescence amplification method for silicon. The metasurface designed by the physicists can enhance silicon's ability to absorb and emit light by 10,000 times – at a record-low volume of the material. The discovery will open the way for faster and more energy-efficient communication devices, as well as nanospectroscopy devices for medicine, science, and industry. The study was published in ACS Photonics.

• ITMO Researchers Learn to Quick Control Metasurfaces With Light

  A team of researchers from ITMO University, Polytechnic University of Milan (Italy), and the University of Brescia (Italy) have developed a new approach to control the properties of metasurfaces using laser radiation. The method allows scientists to switch optical states within a picosecond, which means that they can now transmit more data in less time and build a photonic computer and more accurate medical sensors. The results of the study are published in Light: Science & Applications.

• ITMO Researchers Create Next-Gen Light-Emitting Components for Displays

  Researchers from ITMO University and the Pohang University of Science and Technology (POSTECH) in South Korea have merged a metasurface and a 2D semiconductor to produce a next-gen light-emitting element that is 1,600 times brighter than a semiconductor surface and even more durable and thinner than same-brightness analogs. The new material will pave the way for ultra-thin screens and other optical devices. The resulting paper was published in Light: Science & Applications.

• ITMO Researchers Discover New Properties of Metasurfaces Thanks to Ultrashort Pulse Lasers

  A group of researchers from ITMO University, the Australian National University, and the Friedrich Schiller University Jena (Germany) has for the first time demonstrated effective generation of higher harmonics in silicon metasurfaces. This result was achieved due to resonant states with long lifetimes. The new discovery brings closer the creation of attosecond radiation sources based on semiconductor nanostructures. Ultrashort pulse lasers which earned their pioneers the Nobel Prize in Physics in 2018 make it possible to excite and explore very rapid processes in nature and matter. This opens new horizons for understanding ultrafast physics and faster information recording.

• Invisible Material: Researchers Model Metasurfaces in Hybrid Anapole Modes for the First Time

  Global trends are leaning towards miniaturization, minimalism, and portability – and that's the case for research, too. These days, metasurfaces are gaining popularity as platforms for super-thin devices equal, or sometimes superior to, their "normal-sized" counterparts. This is achieved thanks to “invisible” particles in anapole modes. Recently, these particles have revolutionized nanophotonics, but researchers from ITMO, Moscow, and Riga went even further and developed hybrid anapole modes. Their new model is more efficient than its predecessors and opens new applications for metasurfaces in optics.
