Abstract
We describe a dual-core microstructured optical fiber designed for refractive index sensing of fluids. We show
that by using the exponential dependence of intercore coupling on analyte refractive index, both large range
and high sensitivity can be achieved in the one device. We also show that selective filling of the microstructure
with analyte can increase the device sensitivity by approximately 1 order of magnitude.
