• ITMO Scientists Discover Nonlinear Circular Dichroism in Mie-Resonant Nanoparticle Dimers

  The discovered effect may potentially be used to create special sensors for chiral molecules. These molecules are particularly useful to the pharmaceutical industry, but have a unique structure that makes them difficult to detect. The related article was published in Nano Letters.

• Physicists Trap Light in Nanoresonators for Record Time

  An international team of researchers from ITMO University, the Australian National University, and Korea University have experimentally trapped an electromagnetic wave in a gallium arsenide nanoresonator a few hundred nanometers in size for a record-breaking time. Earlier attempts to trap light for such a long time have only been successful with much larger resonators. In addition, the researchers have provided experimental proof that this resonator may be used as a basis for an efficient light frequency nanoconverter. The results of this research have raised great interest among the scientific community and were published in Science, one of the world’s leading academic journals. Scientists have suggested drastically new opportunities for subwavelength optics and nanophotonics – including the development of compact sensors, night vision devices, and optical data transmission technologies.
