Technology of Polymer Microtips' Manufacturing on the Ends of Multi-Mode Optical Fibers

The technology of polymer microtips' manufacturing on the ends of selected multi-mode fibers has been reported. The study's key element was an extended description of technology parameters' influence on the shape of these 3D microstructures. Basic technology parameters such as spectral characteristics of the light source, monomer mixture type, optical power, and exposure time were taken under consideration. Depending on those parameters, different shapes, sizes, and surface structures of microtips were obtained. The spectral characteristics of the light and optical power delivered to a monomer drop were identified as the most important parameters for the formation of the desired 3D shape of the microtip. Presented experimental results are the base for further studies directed to the application of these micro-elements in the fields of optical measurements and sensors' technology.
