| Abstract | This report summarizes the international collaborative research under the IREE program carried out in the Optical Fiber Technology Center (OFTC) at the University of Sydney, Australia. Microstructured optical fibers are emerging photonic devices with potential to revitalize the entire fiber optical industry. Using photonic bandgap structure, light can be confined in both hollow and pure silica fiber cores without the need of dopant to increase the refractive index of the fiber core. However, these fibers present uniques challenges for the laser fabrication of fiber grating since pure fused silica has very weak photosensitivity. Teaming up with researchers in the OFTC, both vacuum ultra-violet and ultrafast laser have been used to induce fiber grating in pure silica core air-hole microstructured fibers. Grating inscribed in the pure silica core exhibit excellent high temperature stability. Fiber Bragg gratings in air-hole microstructured fibers have been successfully inscribed in various air-hole microstructured fiber for sensing applications. In addition, Pitt’s researchers also worked with OFTC’s scientists on fiber poling research and design and packaging microstructured fiber devices. |
