Abstract

We propose the hetero-core fiber optic refractive index sensor using ITO nano-particles. The hetero-core optical fiber has a structure that leaks transmitted light while maintaining mechanical strength. The ITO is well-known to have an absorption band in the infrared region. The ITO nano-particles were formed on the fiber by the wet process. We have experimentally confirmed that the ITO nano-particles hetero-core fiber sensor causes a change in transmission loss at refractive index in the near-infrared region. Therefore, we demonstrated the fiber optic refractive index sensor using the ITO nano-particles film only in the infrared region.
