Abstract

In this paper, we report on a simple process of fabrication of micrometer-sized polymer elements (microtips) at the extremities of different type optical fibers, including: standard single mode (SMF-28E+, SM-450), photonic crystal (LMA-10), and polymer (GIPOF-62) ones. The method of microtips manufacturing is based on the phenomenon of photopolymerization which is successfully used for the first time, to the best of our knowledge, to manufacture microtips at photonic crystal and polymer fibers. We discuss the influence of the initial process parameters on the final microtip characteristics (i.e., length, diameter, and profile). The potential applications of such polymer microtips are near-field scanning optical microscopy, coupling light sources with fibers, and sensing.
