Abstract
A C2H5OH gas sensor based on a LPFG coated with the TiO2 nano-film is presented.Based on LPmodes,the four-layer model is studied the change of the effective refractive indics and the resonance wavelength of cladding modes as the thickness of overlay increased.The elementary experimental results show that the wavelength of the LPFG loss peak is shifted by ~1.7nm for the case of the TiO2 nano-film of ~80nm in thickness when the concentration of surrounding C2H5OH gas is 1000ppm. And the sensitivity is 1.7 10-3 nm/ppm. The results indicate that the LPFG sensor is highly sensitive to C2H5OH gas and the sensing scheme is feasible.
