Biography

Vladimir Demidov received his Specialist Degree in Fiber Optics from Saint Petersburg National Research University of Information Technologies, Mechanics and Optics in 2010. He joined Research and Technological Institute of Optical Materials, where he passed a few stages of scientific career (from junior researcher to deputy chief of optical fiber department). As a PhD student he worked in the field of development new fiber designs, namely photonic crystal fibers for laser applications. At the moment Vladimir Demidov is leading a group of young scientists focused on development and research (including fabrication and testing) of specialty optical fibers for industry, power engineering, telecommunication and medicine. Over the last couple af years, his group has been working on modeling and experimental verification of linear and nonlinear effects in photonic crystal fibers with radical geometrical distortions for laser physics and sensing applications.

Lecture Title(s)

Leakage Loss Control in Large Mode Area Photonic Crystal Fibers

The lecture will give a comprehensive overview of modal delocalization and discrimination effects taking place in silica-based large mode area photonic crystal fibers of classical and unconventional design. A bunch of efficient techniques for manipulating the loss properties of a few most competitive higher-order LP modes towards pure single-mode, quasi single-mode and few-mode operation will be discussed. The lecture will cover both theoretical and experimental aspects.
