• 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.

• Researchers Present New Synthesis Method for Optically Active Carbon Nanodots

  One of the most remarkable carbon-based nanomaterials are luminescent carbon dots, the physical and chemical properties of which are easy to control. Thanks to their low toxicity, these particles are said to possess great potential in the fields of biology and medicine. Carbon dots are made from organic substances; if their precursor contains a chiral center, the resulting nanoparticles will be chiral, too. These particles have various application prospects, including in medical diagnostics. Researchers from ITMO University and St. Petersburg State University, in collaboration with their international colleagues, have developed a new way to synthesize such nanoparticles with stable optical properties.

• Researchers Demonstrate a Platform for Future Optical Transistors

  Leading research groups in the field of nanophotonics are working toward developing optical transistors –  key components for future optical computers. These devices will process information with photons instead of electrons, thus reducing the heat and increasing the operation speed. However, photons do not interact with each other well, which creates a big problem for microelectronics engineers. A group of researchers from ITMO University, together with colleagues, have come up with a new solution to this problem by creating a planar system where photons couple to other particles, which enables them to interact with each other. The principle demonstrated in their experiment can provide a platform for developing future optical transistors. The results of their work are published in Light: Science & Applications.
