Resumen
A theoretical analysis is presented of a long-period
fiber grating (LPFG) with an overlay of variable refractive index.
The highest sensitivity of the resonance wavelengths to variations
in the refractive index of the overlay can be optimized. There are
two key points for a good design: the selection of an overlay refractive
index close to that of the cladding of the LPFG and the overlay

A theoretical analysis is presented of a long-period
fiber grating (LPFG) with an overlay of variable refractive index.
The highest sensitivity of the resonance wavelengths to variations
in the refractive index of the overlay can be optimized. There are
two key points for a good design: the selection of an overlay refractive
index close to that of the cladding of the LPFG and the overlay
thickness. The problem is analyzed with a numerical method based
on coupled-mode theory. [--]
