On the 26th of April 2023, as part of the Photonics Seminar Series, we will have the pleasure to welcome Dr. Mikhail Melkumov, head of Fiber lasers and amplifiers laboratory of the Dianov Fiber Optics Research Center of the Russian Academy of Sciences (FORC RAS), Moscow.
He will deliver a talk entitled “Bismuth-doped fiber lasers and amplifiers” and give an overview of the current progress in the field of bismuth-doped silica-based fibers, laser and amplifiers, as well as future prospects.
When: On the 26th of April 2023, Wednesday, at 17:00 MSK time
Where: New Campus room E-B2-3007 / BigBlueButton
Mikhail Melkumov graduated from MSU with a degree in Physics and in 2006 obtained his PhD degree from Dianov Fiber Optics Research Center at the Russian Academy of Sciences. Currently he is a head of Fiber lasers and amplifiers laboratory in Dianov FORC RAS which has recently joined Prokhorov General Physics Institute (GPI RAS). His research interests include: Raman, Rear-earth-doped and Bi-doped fibers, fiber lasers and amplifiers, spectroscopy of active centers in silica-based glasses and fibers, radiation resistant active optical fibers. Since 2005 his laboratory has been intensively working on the development of Bi-doped fibers, fiber lasers and amplifiers and is currently a world leader in this field.
Bi-doped fibers are new optical materials providing possibilities of broadband optical amplification in the near IR range where other active fibers doped with Rear Earth elements are inefficient. Variation of glass composition allows one to obtain luminescence and gain associated with Bismuth active centers in the range 1.1-1.8 um. Thus, one of the important applications of such active fibers is in ultrabroadband fiber telecom systems with dense wavelength division multiplexing where bismuth-doped fiber amplifiers (BDFA) help to increase fiber reach and capacity by several times. This talk aims to highlight latest results in the field of bismuth-doped fiber lasers and amplifiers and their possible applications.
