| Outline of Final Research Achievements |
First, we succeeded in filling the core of the hollow-core optical fibers with an electrorheological fluid (ERF) by use of a capillary phenomenon. Subsequently, we made an attempt to detect the Brillouin scattering (caused by weak acoustic waves) signal in these fibers directly using a sensitivity-improved measurement setup, but the optical propagation loss in the ERF was found to be too high for the signal to be detected. We then developed a setup for measuring the acoustic velocity in the ERF using a pulse-echo technique to indirectly calculate its Brillouin scattering properties. Using this setup, we measured the acoustic velocity of the ERF and its dependence on particle concentrations and on electric field intensity. Thus, we have laid the foundation of distributed electromagnetic field sensing using Brillouin scattering in the ERF.
