• ITMO Physicists Discover New Physical Effect

  The scientists called it the anomalous exciton Hall effect. It occurs when a laser affects a semiconductor plate in the presence of a magnetic field. This phenomenon can be potentially used for studying exciton quasiparticles. The research is published in Physical Review Letters.

• 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.

• ITMO Scientists Gets the Presidential Grant on Studying Quasiparticles

  At the end of November, Valentin Milichko, an Associate Professor for the Department of Nanophotonics and Metamaterials has received the Presidential Grant. Now, the scientist has two years to find experimental evidence of the effect of light on excitons in metal-organic crystals. Simply put, if this research is a success, it will not be long before a new generation of computers based on optical transistors will be developed.
