Paper Abstract

In the paper we are looking for these properties of optical fibers which cannot be obtained easily with classical CVD, VAD, PSL, DC and RiT fabrication methods. These properties are: - fibers with minimized environmental sensitivity, - fibers appropriate for embedding, - specially coated fibers and sensitized, - fibers suitable for smart structures and skins, - fibers with angular dependence of refractive properties against long axis, i.e. fibers with no refractive axial symmetry, - fibers with helical cores and with noncircular cores, - multicore optical fibers. We have developed a completely new manufacturing method to obtain comparatively easy most of these abovementioned fibers. The method consists of two main stages: preform preparation and fiber pulling. The preform preparation process consists of two substages: cold and hot. Cold process involves preparing of mo-dular glass rods and whole preform assembling. Hot process involves (optional) computer controlled high temperature diffusion process and consolidation of the preform in an isostatic computer controlled press. We are going to present in the paper some detailes concerning the newely developed mosaic-assembling--defibering (MAD) technology of sensor-oriented optical fibers and sensing imageguides. We will also show some examples of manufactured unique multimode and singlemode optical fibers for sensor applications. The mosaic-assembling-defibering technology of sensing fiberoptic imageguides is subject to patent claim.
