• ITMO Researchers Explore Direct Laser Writing of Nanolattices

  Researchers from ITMO’s Faculty of Nanoelectronics together with their colleagues from the Lebedev Physical Institute, D. Mendeleev University of Chemical Technology of Russia, and the National Research Nuclear University MEPhI have conducted a study that showed that nanolattices possess high spectral selectivity. Their layers can be used as color filters for specific wavelength ranges, and one glass plate can contain records of up to six layers. Using this technology, the scientists were able to implement dispersive birefringent filters, which have multiple applications. For instance, they can be used to create AR/VR color displays or novel biochemical sensors for bacterial analysis.

• Researchers Find Way to Enhance Photon Entanglement

  Scientists from ITMO University figured out how to design more efficient and compact devices for generating pairs of entangled photons. The research team found that the number of entangled photons increased when the light beam passed through a special nanolattice compiled of metal layers. The effect of entanglement is enhanced by a strong electrical field arising in the lattice. Previously, such experiments could not be analyzed theoretically, which is why the new method opens big opportunities in designing a wide range of quantum devices, for example, elements of optical computers and secure communication systems. The results were published in Physical Review Letters.
