Micro-Optics Fabrication on Top of Optical Fibers Using Two-Photon Lithography

Abstract

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> We describe the fabrication of different micro-optical structures on top of optical fibers using two-photon polymerization. We show the convenience of this approach to quickly create generic three-dimensional shapes using a single setup by comparison to previous shape-dependent methods. A set of different structures, designed for different optical functions, are fabricated and characterized to demonstrate the versatility of this approach and their high optical quality. </para>
