This work presents the fabrication of optical fiber
refractometers based on indium tin oxide (ITO) coatings
deposited by sputtering with response in the visible spectral
region. ITO thin-films have been sputtered by employing a
rotating mechanism that enables the fabrication of smooth and
homogeneous coatings onto the optical fiber core. Fabricated
ITO coated optical fiber devices present several resonances in the
visible and near infrared region. These resonances show high
optical power attenuations (more than 10 dB) in the visible
spectral region, which produces changes in the colour of the
output visible light. Therefore, since these resonances shift as a
function of the refractive index (RI) of the surrounding medium
it is feasible to determine the RI of the outer medium in contact
with the ITO coating by simply monitoring the chromatic
coordinates (colour change), x and y, of the visible output light [--]
