Single Mode High Refractive Index Optical Fibres

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.
