Nature Photonics publishes reviews of the discoveries that haven’t been written about by the Nature Publishing Group, but, according to the editors, deserve to be highlighted. Recently, an article written by the staff of ITMO University’s Laboratory of Femtosecond Optics and Femtotechnologies was featured on the list. ITMO.NEWS talked to the head of the laboratory, Anton Tsypkin, about how the discovery was made and what opportunities Nature’s acknowledgment brings.
ITMO graduate Anton Zaytsev who is currently doing a PhD program at the University’s Faculty of Photonics and Optical Information has become one of the six people to receive a scholarship from the IEEE Microwave Theory and Techniques Society for implementing the project “Development of optically tunable graphene-based THz devices”. ITMO.NEWS spoke to Anton to learn how terahertz radiation can replace the X-ray, why he and his colleagues are looking for a replacement for single-layer graphene, and what is to be considered when applying for an international grant.
Terahertz radiation is a type of electromagnetic radiation located within the frequency spectrum between infrared and radio. It passes well through a variety of materials and is harmless to humans, which opens up a wide range of its possible applications. Researchers at ITMO University are actively working on this subject in collaboration with their French colleagues. Together, the scientists are developing a pulsed terahertz spectrometer for application in the analysis and restoration of artworks. Read more about the project and how terahertz technology lets scientists explore art in the article below.
The staff of ITMO University’s International Laboratory of Femtosecond Optics and Femtotechnologies have recently published an article in a prestigious journal Scientific Reports. Their work explores the advantages of the Z-scan method with pulsed terahertz radiation. Based on the results of their research, the scientists proposed a set of recommendations for future studies of nonlinear properties of terahertz radiation. Read on to learn more about the authors of the article and practical applications of their work.
Researchers from ITMO University have, for the first time in history, managed to directly measure the nonlinear refractive index of matter in the terahertz range. The results of their experiments were compared with previously existing theoretical predictions in order to confirm the presence of nonlinear effects. The obtained data can be used to control light, as well as in fundamental and biomedical research. The results have been published in Optics Express.
Terahertz technologies hail a new era where blood tests are much more accurate, and Internet faster. All this is thanks to nanomaterials and their unique properties. One of the leading researchers in this field, Ilya Anoshkin joined ITMO University’s teaching staff via the ITMO Fellowship program. In spite of his extensive and successful experience of working in Finland and Sweden, he is reluctant to call himself a scientist. ITMO.NEWS met Ilya to find out why, and to talk about the technologies of the future and his take on teaching at ITMO.
A research team from ITMO University and the University of Rochester (the USA) have conducted a study on the formation of terahertz radiation in liquids. Previously, the generation of such radiation in a liquid medium was considered impossible due to high absorption. However, in their new research, the scientists described this phenomenon’s physical nature and demonstrated that liquid radiation sources can be equally effective to traditional ones. The results have been published in Applied Physics Letters.
