  • 2D into 3D: Optical Holography Founder Yuri Denisyuk and His Legacy

    Russian science was moved forward not only by great singular minds, but sometimes by dynasties of talented researchers. One such example is the dynasty started by one of the founders of optical holography, Yuri Denisyuk, whose name is still remembered both in Russia and abroad. His son, Igor Denisyuk, chose to follow in his footsteps: he has spent over 20 years working at ITMO, creating high-concentration nanocomposites as well as anti-counterfeiting holograms based on this technology. For this Russian Science Day, we talked with Igor Denisyuk about the path of a scientist, the rise of optical holography in Russia, and ways to develop succession in science.

  • What To See at ITMO’s Museum of Optics This Winter Break

    The building located on Birzhevaya Liniya 14 has a rich history: in the early 1860s, it was owned by the Eliseevsky merchant dynasty, and since the 1920s, it has housed a state optical institution, where a graduate of ITMO University recorded the first-ever 3D art hologram. The structure now houses ITMO's Museum of Optics – the first university-based interactive museum that not only introduces visitors to cultural heritage items but also lets them practically feel the magic of science. Here are the top exhibits to see at the museum.

  • Metaphotonics Review by ITMO Scientists Among Top 1% Most Cited Papers

    A publication by researchers from ITMO and the Australian National University is among the top 1% of the most cited papers on optics according to the bibliometric system Web of Science (WoS). The paper reviews applications of machine learning and AI in metaphotonics, a new subject field that may pave the way for a whole new class of next-gen devices.

  • ITMO Scientists Create Improved Optical Module for AR Devices

    Researchers from ITMO have used volume holography to develop an optical module that is resistant to chemical damage, physical impact, and extreme temperatures. This module, called a combiner, can be used to create industrial-purpose AR glasses or to project interfaces directly onto the windshields of cars and airplanes. Unlike its counterparts, the device is single-layered, which makes it lighter and prevents glare. The project is supported by the Priority 2030 program.

  • ITMO Researchers Develop Simple Technology for Fabrication of Microfluidic Elements on Glass

    Scientists from ITMO’s Institute of Laser Technologies have developed a new technology that creates structured microfluidic elements, including channels, reservoirs, and spirals, on a silica surface. Importantly, the novel fabrication method requires only a laser and a single operator, while the resulting structures can be used in microfluidic chips for biomedical research and diagnostics of cancer, diabetes, and cardiac impairments. The results of the study are described in a recent article in Optical and Quantum Electronics.

  • ITMO Scientists Develop Ultracompact Optical Switch

    The new device includes a structure of single-atom semiconductors and an ultracompact nanoresonator. The switching is conducted with light, via changes in the exciton states in each of the two semiconductor layers. Thanks to its ultracompact size (10 nanometers long and 1.5 nanometers thick), the device can be placed on a chip for use as a logic element in computers for optical information processing. The results of this study, conducted in collaboration with Pohang University of Science and Technology (POSTECH, South Korea), are described in an article published in ACS Nano.

  • Bright Ideas: ITMO Researchers’ Dynamic Nanostructure Achieves 35x Light Amplification

    The staff of ITMO University’s Faculty of Physics have developed a dynamic nanostructure that changes its optical properties in response to external stimuli. At its core is a polymer that expands and contracts based on its temperature. The researchers have shown that nanostructures containing silicon nanoparticles can amplify light seven-fold – and the number blows up to 35 when the material is combined with gold. What’s more, the polymer can change its form an unlimited amount of times. Its potential uses include the development of automated heat sensors and various other smart devices.

  • Svetoskop Museum of Fascinating Physics Launches in Kronstadt With ITMO Support

    How to fly using optical illusions, why white clothes glow bright under UV light, and how to put planes in the air with the energy of light – these and other things are explained at the Svetoskop Museum of Fascinating Physics, which has just opened in a new public space in the town of Kronstadt near St. Petersburg. Supported by ITMO, the museum helps its guests not only experience, but also to get to the bottom of various optical and mechanical phenomena – and even stage their own experiments.
