NSU Scientists Investigate Microresonators

As part of a project supported by the Russian Science Foundation (No. 22-12-20015), a team of eight young scientists and students from Novosibirsk State University is exploring a new type of microresonator. They are easy to manufacture compared to analogues and have a number of features that simplify their use. The specialists at the youth laboratory emphasize they are not working with ready-made devices that use light for analysis. They are studying a new object that is currently not a part of what is generally accepted but has the possibility of becoming widely used in the future. 

Ilya Vatnik, Ph.D., explained, 

The novelty of our work is that we are studying cylinder-shaped microresonators. For the cylinder, we use a standard optical fiber that is traditionally used to provide Internet to residential buildings. It costs only a few rubles per meter. We use it in an unusual way because of its shape we can launch light differently than other scientists do so the radiation does not propagate along the axis of the fiber along its core, but in a circle along the edge of the cylinder. This becomes not just a light-conducting fishing line, but a microresonator. 

This microresonator can be used to measure the chemical composition of substances and objects, radars, machine vision on cars, and much more. 

By the way, while developing the theory of cylindrical microresonators, Alena Kolesnikova, a Junior Researcher at the Laboratory and a 1st year postgraduate student at the NSU Department of Physics, received the news she was awarded the Mikhail Gorodetsky Prize at the Russian Quantum Center.
