| Outline of Final Research Achievements |
In this study, to apply our novel nanofiber structure fabricated by the focused ion beam milling and chemical wet etching for optical sensing, we demonstrated the sensing of liquids with different refractive index by monitoring transmission spectrum. The propagation modes in nanofiber are changed from the mode in normal fiber section because of the tapering of core. So, when we detect the mode change due to the cladding environment, we can estimate the refractive index of cladding material in micron-sized area by evaluating the transmission spectrum. We can use such mechanisms for the in-line nanofiber optical sensing. Furthermore, We investigated the introduction of the photonic crystal and metal nano structures to the optical nanofibers which enhanced the sensibility of optical sensing.
