Opis:: The present paper is focussed on the search of technology of new kinds of optical fibers characterised by good magnetooptical properties. The elaborated optical fibres are to apply in optical sensors of electric current and the magnetic field. In result of these researches and analyses a new optical fibre was put forward. Such optical fibers were designed, produced and subjected to extensive tests. This paper presents the results of investigations that were carried out as well as the parameters of the tested structures.

Opis:: Temperature dependence of the mode dispersion is investigated for commercially available polymethyl methacrylate (PMMA) based step-index polymer optical fibers. An analytical expression is proposed describing the thermal variation of the fiber refractive index. This index decreases with increasing temperature as density of the polymer material drops. The study covered the temperature range from -60°C to 100°C. Results show that the modal dispersion decreases and the bandwidth increases with rising temperature.

Opis:: Using the power flow equation, we have examined mode coupling in a step-index multimode glass optical fiber. As a result, the coupling length at which the equilibrium mode distribution is achieved and the length of fiber required for achieving the steady-state mode distribution are obtained. These lengths are much longer for glass fiber than they are for plastic optical fibers. Our results are in good agreement with experimental results reported earlier.

Opis:: We studied the polarization properties of four photonic band gap fibers with elliptical core and different cladding geometries. To do so we relied on a fully vectorial calculation method, which uses a hybrid edge/nodal finite element approach with perfectly matched layer absorbing boundary conditions. We determined the spectral dependence of the confinement loss for the fundamental modes of orthogonal polarizations. Our results show that, for the four structures studied, the polarization dependent loss is so high that they can be used as fiber-optic polarizers in the full band gap range.
