Annotation
In this paper, we present the numerical analysis of modal coupling properties and resonance spectral response of long-period gratings (LPGs) in solid-core photonic crystal fiber (PCF) with respect to their sensitivity to refractive indices of the measurands in the air channels using a full-vectorial frequency-domain method. The calculated results show that wavelength resonance of a PCF-LPG can be extremely sensitive to the refractive index change.
