Global trends are leaning towards miniaturization, minimalism, and portability – and that's the case for research, too. These days, metasurfaces are gaining popularity as platforms for super-thin devices equal, or sometimes superior to, their "normal-sized" counterparts. This is achieved thanks to “invisible” particles in anapole modes. Recently, these particles have revolutionized nanophotonics, but researchers from ITMO, Moscow, and Riga went even further and developed hybrid anapole modes. Their new model is more efficient than its predecessors and opens new applications for metasurfaces in optics.
Perovskites are a class of semiconductors that are being actively researched in light of their unique physical properties. In the past decade, solar cells based on these materials have attained a commercial level of effectiveness. In a new study, researchers from ITMO have presented a prototype version of a photodetector based on carbon nanotubes and perovskites. ITMO.NEWS spoke with the authors to find out what new prospects for flexible electronics the project offers.
Pavel Tonkaev started his Master’s at ITMO University in 2017 after graduating from Peter the Great St. Petersburg Polytechnic University (SPbPU). Since his second year here, Pavel has been studying perovskite materials in nanophotonics and optoelectronics. Current studies suggest that these materials may not only become the future of solar energy but also set the stage for various other technologies, from the creation of sensitive photodetectors to the study of living cells. In this article, Pavel talks about how to get into research in the second year of your Bachelor's, how his discoveries can help people in the future, and why scientists shouldn’t stick to one perspective.
Every year, the December issue of Optics & Photonics News includes a list of the year’s 30 most impactful studies in the field of optics and photonics. This year, it features research by scientists from ITMO University who have succeeded in demonstrating record-breaking efficiency in light coupling at large incidence angles. ITMO.NEWS spoke to Oleh Yermakov, one of the authors of the study and a researcher at the university’s Faculty of Physics, to find out how the team plans to develop their research in the future.
ITMO University Hosts METANANO 2021: Poster Sessions in Gather.Town and Even More International Participants
METANANO is the only conference in Russia that focuses on nanophotonics and metamaterials. It is organized by ITMO’s School of Physics and Engineering and the Mediterranean Institute of Fundamental Physics and annually attracts hundreds of researchers from Europe, Asia, the USA, and Russia. Read on to learn what the conference was like this year and how it is different from classic scientific events.
A research team that includes staff members of ITMO University has suggested a new method of processing miniature perovskite fragments. The method is cheap and makes it possible to fashion microcrystals into desired shapes for use in production of lenses and other optoelectronic elements. This will help bring about the material’s widespread adoption within the industry. A paper on the research was published in Laser & Photonics Reviews.
A team of Russian scientists including researchers from ITMO University, A.M. Prokhorov General Physics Institute, the Institute for Physics of Microstructures of the Russian Academy of Sciences, Skolkovo Institute of Science and Technology, and Lomonosov Moscow State University succeeded in enhancing the luminance of quantum dots on a silicon substrate. The methods used by the scientists can help create next generation microchips that will receive and transfer information from a computer to a fiber-optic network a lot faster. The article was published in Laser & Photonics Review.
ITMO Scientist Andrey Bogdanov Receives Euler Prize from the Government of St. Petersburg and the Russian Academy of Sciences
Andrey Bogdanov, a senior research associate at ITMO’s Faculty of Physics and the head of the Nanophotonics and Metamaterials Master’s program, was recognized by the Government of St. Petersburg and the city’s Scientific Center for his contribution to science.
Sergey Makarov is one of the youngest DSc holders at ITMO University. Together with Anvar Zakhidov, a professor at the University of Texas in Dallas, he led the formation of ITMO’s Laboratory of Hybrid Nanophotonics and Optoelectronics. Sergey has been nominated for various awards, including the President of Russia Award for Young Scientists in the Field of Science and Innovation and Research Excellence Award Russia as the youngest and most productive author in materials sciences. Not only does he run the laboratory, conduct research, and publish articles but also organizes conferences and international schools, and works as an editor in two scientific journals. ITMO.NEWS talked to Sergey to learn more about how to succeed in science, why it is important to reach out to the widest audience, what football players and scientists have in common, and whether it is possible to research on your own.
This will potentially allow them to create more compact and efficient elements for lasers, sensors, and optical chips. Moreover, it proves the hypothesis that ITMO physicists had about the connection between a material’s refractive index and its electronic features. The research has been published in Nanophotonics.
