Abstract
Abstract The Conference on Optical Fibers and Their Applications, Nałȩczów 2012, in its 14th edition, which has been organized since more than 35 years, has summarized the achievements of the local optical fiber technology community, for the last year and a half. The conference specializes in developments of optical fiber technology, glass and polymer, classical and microstructured, passive and active. The event gathered around 100 participants. There were shown 60 presentations of 20 research and application groups active in fiber photonics, originating from academia and industry. Topical tracks of the Conference were: photonic materials, planar waveguides, passive and active optical fibers, propagation theory in nonstandard optical fibers, and new constructions of optical fibers. A panel discussion concerned teaching in fiber photonics. The conference was accompanied by a school on Optical Fiber Technology. The paper summarizes the chosen main topical tracks of the conference on Optical Fibers and Their Applications, Nałȩczów 2012. The papers from the conference presentations will be published in Proc. SPIE, including a conference version of this paper. The next conference of this series is scheduled for January 2014 in Białowie˙za.

Nałeczów meetings are focused on photonics materials engineering, technologies, construction and theory of optical fibers
The conference is organized by Białystok University of Technology (Faculty of Electrical Engineering) – in Białowieza, and UMCS (Laboratory of Optical Fiber Technology) together with Lublin University of Technology (Institute of Electronics and Information Technologies)
Summary
Microstructural, are made of glass or polymers. Microstructural construction, in a form of a two dimensional matrix which builds the structure of a photonic crystal, is a basis of photonic bandgap limited propagation of the EM wave in the fiber. The involved phenomena may be: change of the propagation mechanism from optical to photonic and vice versa, possibility to propagate and tuning photonic bandgaps in the transmission spectrum of the nonlinear fiber, dynamic filtration, fast tunable attenuation characteristic, tunable retardance – phase delay between orthogonal polarization components of the propagated fundamental mode. Impregnation of a microstructural fiber (or other photonic structure) with ferroelectric fluid of high refraction (the level of refraction is referred in such cases to a pure silica glass) causes generation in the material a tunable photonic mechanism of light propagation. One of the researched functional photonic components done on the liquid crystal fiber is a tunable, fully optical fiber polarizer Such a polarizer was build at the Faculty of Physics WUT. There was performed a control system of the optical fiber polarizer with four electrodes, of pairs rotated against each other by π/4
