Specialty fibers have complex structures due to their geometry, including glass core and cladding, multilayered polymer coatings, and the variations of their elemental compositions. Such complex structures of the specialty and microstructured fibers with air holes and the deformation due to manufacturing fiber lasers during fiber splicing can be investigated by X-ray computed tomography (XCT). The fiber fabrication process includes deposition and post-processes with a subsequent fiber drawing. Here, we present the first official results performed at the station BEATS, SESAME, for the synchrotron XCT imaging of specialty optical fibers all in one, such as polarization-maintaining, active, and photonic crystal fibers. In addition, temperature-dependent XCT measurements provided information on how inner structures, such as polymer coatings, could evolve for PM fibers. The conditions of the XCT measurements and the inner structure of the same type of fibers were found to be crucial and act as the guidelines that will be presented for the structures with sizes close to the voxel size.
