2023: Development of optical fibers for quantum communications

Holding Schwabe"" State Corporation Rostec and a team of young scientists, Volga State University of Telecommunications and Informatics (PGUTI g.) Samara Are working on joint projects to develop new classes. optical fibers Materials that provide a reliable connection when creating networks telecommunication are used in the development of high-tech optical devices, including in systems. quantum communications Rostec announced this on March 23, 2023.

One of the key results of the intellectual cooperation between Schwabe and PGUTI was the creation of a group of microstructured fiber fibers, characterized by induced chirality - longitudinal twisting. Such materials are used in various industries of photonics and sensorics. For example, when creating optical tweezers, fiber-optic sensors, as well as "generators" of optical vortices, the latter are especially relevant for quantum communications systems.

As of March 2023, optical fibers are quite actively displacing copper cables used earlier in telemetry, telemechanics and other private practical applications of on-board and industrial data transmission networks. The fiber is lighter in weight, more compact in installation, immune to electromagnetic interference and, most importantly, has a significantly large bandwidth. Cooperation between Schwabe and PGUTI takes place in fact at the junction of science and industry. This interaction allows you to create new types of optical fiber, expand its scope, - said the executive director of Rostec Oleg Yevtushenko.

Another joint development of the Schwabe enterprise and PGUTI is a class of quartz optical fibers with an extremely increased core diameter - up to 100 microns instead of the typical 50 and 62.5 microns. Due to this, the fiber provides high reliability of the data transmission network in conditions of vibration and possible presence of dust and suspensions in the environment. The material is optimized for cooperation with laser optical radiation sources in the equipment of multi-gigabit data transmission networks of various purposes.

Such fiber is primarily focused on cable systems operating in aggressive operating conditions, and can be used, for example, in aircraft, spacecraft, railway locomotives, passenger and freight trains, in the subway, as well as in industrial networks.
