We present experimental results on the fabrication and characterization of photonic structures on ultrathin optical fibers. They are realized from standard optical fibers which are flame heated while simultaneously pulling to produce a waist with a diameter of 500 nm. The photonic structure is then carved out of the ultrathin part of the fiber using focused ion beam milling (FIB). The optical properties are spectrally characterized by transmission and reflection measurements. Our current focus lies on the improvement of the periodicity and the reflectivity of the photonic structures and their use for realizing ultra-low mode-volume optical microresonators.
