abstract = {Surface plasmons are a revolution in nanophotonics
because they permit the transport of energy along
metal-dielectric interfaces, something which is of vital importance
in sensorswhichmeasure refractive indexes. The aim of
this research has been the design and optimization of several
surface plasmon resonance (SPR) sensors to measure the
refractive index of a solution of sucrose and water (BRIX
degree) in real time. The optimization and design of these
sensors was made from the theoretical modelling of the
reflectance curves, which has allowed us to determine which
the most favourable configuration is. The sensors proposed
are modulated in intensity and they have the advantage of not
having mobile parts, so, their lifetime is longer.We propose a
plasmonic sensors (three-in-one) formeasuring different sucrose concentrations.As the refractive indexes vary very little
with the concentration, we have designed a three-in-one sensor to cover all concentrations from 0-80% BRIX degree. The
proposed sensors operate by ranges of refractive indexes (low, medium and high). They are made up of a hemispherical
prism and a layer of gold following the Kretschmann configuration. The sensor working in the low zone has a sensitivity
of between 22.95 and 4.64RIU−1 and a resolution of between 4.3 × 10−4 and 8.7 × 10−5RIU, the one used for the medium
zone has a sensitivity of between 21.05 and 3.89RIU−1 and a resolution of between 5.1 × 10−4 and 9.5 × 10−5RIU, and
the one for the high zone has a sensitivity of between 19.60 and 4.64RIU−1 and a resolution of between 4.3 × 10−4 and
1.0 × 10−4RIU.},
