Abstract
In this work, fiber-optic voltage sensors based on the deposition of gold nanocoatings, either in form of nanoparticles or planar thin-films are reported. A first optrode is manufactured by using in-situ synthesis of gold nanoparticles within a polymer matrix, leading to localized surface plasmon resonances. The second probe is manufactured by sputtering a planar gold thin-film onto the optical fiber. The obtained results confirm the possibility of detecting electrical events by means of plasmonic optical fiber sensors with sensitivities ranging from 0.05dB/V in the case of LSPRs to 0.12dB/V in the case of SPRs.
