Design and techology for special fiber with minimal outer diameter,

design and technology of the miniature in-line components (coupler, polarizer) based on

special fiber.

For most of fiber optic interferometric (fiber optic gyroscopes, fiber optic probes) or polarimetric (Faraday magnetometer) sensors, the small size is technical advantage providing easier installation, universality adn adaptation. Fiber optic sensor is an assembly comprising optical fiber and set of connected in a certain sequence fiber optic components like couplers (splitters), polarizers, light modules, photoreceiving modules, etc.

External diameter of the quartz fiber determines the size of basic componets operating on evanisient wave principle (polarizer, coupler). By using the fiber with standard diameter (125 microns or 80 microns) the possible beding radius of fiber and size of components are rather large preventing building of miniature fiber optic assemblies and final sensing devices.

The proposed project is aimed to develop optical "slender" PP fiber - polarization maintaining, reduced to 40 micron outer diameter, which is suitable for fusion-tapering technique for components fabrication. Main components - coupler, polarizer - will be miniaturized and their performances will be investigated.

Miniature variants of common fiber optic interferometric sensors will be created and tested. Fiber optic components miniaturization limits will be explored by way of trying fiber fabrication with minimal outer diamter (in the range of 15 - 30 microns).
