This study demonstrates the coupling between the backward cladding mode and the backward core mode in a fiber Bragg grating (FBG) cascaded with a long period grating (LPG) to create induced wavelength channels for detecting refractive index variation. Cladding-to-core mode coupling is based on the phase matching condition in which the wave vector of the LPG is equal to the difference between the backward...
A fiber sensing head based on an FBG concatenated with an LPG is proposed with the advantages of simplicity and easy fabrication for applying in index sensing systems.
This paper considers the problem of correlation analysis using correlation coefficient and Random Forest. Although Random Forest is a function estimation algorithm, it provides two extra information about independent variables importance according to dependent one and partial dependence. Thus influencing order of correlative factors comes out. The limitation of correlation coefficient of only two...
A high sensitivity liquid refraction index fiberoptic sensor based on a multimode air-gap long period fiber grating is experimentally demonstrated with the sensitivity of 1063.737 nm and 702.032 nm per unit index for the sugar-solution and the salt-solution respectively.
