| Abstract: | The sensing characteristics of long-period fiber grating(LPFG) resonance wavelength shift owing to transverse load are theoretically analyzed,by considering influential factors such as strain-optic effect and the change of wave guide structure.The characteristics include the resonant wavelength shift and the interval between two resonant sub-peaks(namely transmission sub-pits) split in LPFG spectrum.According to the analytical properties,the sensitivity coefficients of the resonant wavelength shifts and the... |
