The origin of the entire modern Fiber Optics Research Center

Historically, the Fiber Optics Laboratory is the oldest laboratory, which can be considered the origin of the entire modern Fiber Optics Research Center. In the 1970s, future Academician E.M. Dianov headed a small group of researchers within the Lebedev Physical Institute/General Physics Institute. This group quickly expanded in terms of staff and research areas, becoming a sector, then a laboratory, a department, and finally the Fiber Optics Research Center. The rapid development of fiber optics worldwide has contributed to a significant increase in the number of research areas, and, as a result, to the emergence of new research laboratories focused on developing specific areas of fiber optics (currently, the Fiber Optics Research Center of the Russian Academy of Sciences has seven fully-fledged research laboratories). The LVO has nurtured the scientific talents of many renowned scientists, who continue to work successfully at various universities and research departments of large companies around the world.
The LVO's research focus has constantly evolved, consistent with Academician E.M. Dianov's fundamental principles of conducting cutting-edge research in relevant areas of fiber optics. Currently, the LVO's research is conducted in the following main areas:

• physical mechanisms of photosensitivity in fiber optics of various compositions and structures;
• fiber refractive index gratings: recording technologies, properties, and applications;
• narrow-band fiber lasers, including single-frequency and random fiber lasers;
• fiber lasers on active ions in phosphosilicate matrices;
• fiber-optic sensors of various types, including sensors with high thermal and radiation resistance;
• fiber optics based on non-quartz glass (germanate glass, nickel-doped glass ceramics).

Laboratory staff actively participate in joint research with other laboratories of the FORC RAS and with other scientific organizations in Russia and abroad.
