| Outline of Final Research Achievements |
We fabricated functional fiber devices (optics attenuators and long period fiber gratings) by controlling air hole diameters in polarization-maintaining photonics crystal fibers (in which air holes are arranged in two-fold rotational symmetrically around their centers of cross-sections) using carbon dioxide laser irradiation. In the optical attenuator fabrications, it was demonstrated that the desired attenuation could be obtained by laser power control and that the attenuation could be varied using fiber bending. In the long period grating fabrications, attenuation peaks corresponding two polarization modes were obtained in the transmission spectrum. The fabricated fiber devices are applicable not only to fiber optic communication systems but also to optical sensing systems.
