Abstract
We report the design and fabrication of a multilayered macroscopic fiber preform and the subsequent drawing and optical characterization of extended lengths of omnidirectional dielectric mirror fibers with submicrometer layer thickness. A pair of glassy materials with substantially different indices of refraction, but with similar thermomechanical properties, was used to construct 21 layers of alternating refractive index surrounding a tough polymer core. Large directional photonic band gaps and high reflection efficiencies comparable to those of the best metallic reflectors were obtained. Potential applications of these fibers include woven fabrics for radiation barriers, spectral authentication of cloth, and filters for telecommunications.

- PES films were purchased from the Goodfellow Corporation and As 2 Se 3 (99.999% pure metals basis) was purchased from Alfa Aesar/Strem Chemicals. A 2-cm-OD PES rod was made from a PES film of 50 ± 5 μm that was rolled by hand onto a 7-mm hollow borosilicate glass tube and consolidated through heat treatment at 261° to 263°C under vacuum for ∼25 min. As 2 Se 3 films were deposited by thermal evaporation with a vacuum evaporator (Ladd Industries) on a separate PES film. In situ layer thickness monitoring was carried out with a crystal thickness monitor (Sycon STM100) that was calibrated with a surface profilometer (Tencor P10). An As 2 Se 3 film of 6.5 ± 0.4 μm was evaporated at a rate of ∼10 nm/s on each side of a thin PES film of 25 ± 2 μm. This As 2 Se 3 -coated film was then rolled onto the outside of the previously fabricated PES tube and consolidated with a similar vacuum thermal treatment. The hollow Pyrex tube at the core of the PES/As 2 Se 3 structure was then etched out with hydrofluoric acid.
- The preform was lowered at a controlled rate into a three-zone vertical tube furnace (Thermcraft) and pulled from below at controlled speeds with a motorized capstan (Heathway). Fiber diameters were monitored with laser diameter monitors (Beta LaserMike). Fibers were drawn at a central-zone maximum temperature of 295°C at speeds ranging from approximately 1 to 10 m/min depending on target fiber diameter. The upper zone of the furnace was heated to 240°C and the lower zone was unheated but drifted to a temperature of ∼150°C.
- The applicability of the indicated angular range of detection was corroborated by personal communication with M. Friedman of SpectraTech.
