St. Petersburg Scientists Propose Using Terahertz Holography for Diabetes Tests
Scientists from ITMO University and Almazov National Medical Research Centre have put forward a new way for diagnosing diabetes. It is based on the fact that the blood of people with diabetes has a different response in the terahertz range than that of people without this condition. More in this article by ITMO.NEWS.

ITMO Researchers Develop New Terahertz Pulse-Based Data Encoding Method
Researchers around the world are working on ways to transfer data in the terahertz (THz) range, which would make it possible to send and receive information much faster than what is allowed by today’s technology. But the issue they’re facing is that it is much more difficult to encode data in the THz range than in the GHz range, which is currently used by 5G tech. A group of scientists from ITMO University have demonstrated the possibility of modifying terahertz pulses in order to use them for data transmission. An article on this subject was published in Scientific Reports.

ITMO University Researchers Organize Symposium on Terahertz Photonics in Paris
In December 2019, Paris hosted the Smart NanoMaterials (SNAIA2019) international conference, which brought together specialists in the field of nanophotonics, optoelectronics, quantum calculations and others. Supporting the conference was ITMO University, which organized a symposium chaired by Olga Smolyanskaya, an associate professor at the Faculty of Photonics and Optical Information and head of the Laboratory of Femtomedicine. In the course of two days, the participants of the symposium, researchers from Russia, France, the UK and other countries, discussed the latest trends in the field of terahertz technologies and shared the results of their research with each other.

ITMO Scientists’ Research Featured by Nature Photonics
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.

IEEE Scholarship Winner on Opportunities Offered by Terahertz Radiation
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.

How Russian and French Researchers are Helping to Restore Classic Art
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.

ITMO Scientists Make First-Ever Measurement of Nonlinearity in Terahertz Frequency Range
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.

ITMO Fellow Ilya Anoshkin on Nanotubes and Working Abroad
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.

Physicists Conduct Study of Terahertz Radiation in Liquids
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.
