Abstract:
According to the Coarse Wavelength Division Multiplexing (CWDM) wavelength dependent transmission characteristics, a wide range fiber Bragg grating (FBG) demodulation method is proposed and experimentally demonstrated in this paper. The relationship between system input and output is obtained through analysis, and verified experimentally. Particularly the influence of light source power on demodulation precision and calibration value is analyzed. The wavelength demodulation range of the system is about 10 nm, which can realize the measurement of 8000με; The precision can be 3~5 pm. Since the system is compact, low cost and passive, it is able to be integrated as a portable demodulation module.
