RT Book, Section T1 Extension of Surface Plasmon Resonance in fiber optic sensors into the visible region A1 Navarrete Fernández, María Cruz A1 Díaz Herrera, Natalia A1 González Cano, Agustín A1 Esteban Martínez, Óscar AB In this work we experimentally show how the technology of surface plasmon resonance (SPR) in doubly deposited uniform-waist tapered optical fiber sensors (DLUWTs) can be extended into the visible region (around 520 nm) by changing the thicknesses of the deposited layers. In this way, by using DLUWTs we can cover, in an easy and versatile way, a total wavelength range over 1000 nm wide, having shown in the past how this same kind of sensors can be usable in the communication band. The possibilities of fiber sensors can then be applied to the region of visible wavelengths, which is very interesting from the biological point of view.
