A novel demodulation of chirped fiber Bragg gratings using optical power measurement

Demodulation is a bottleneck of application of chirped fiber Bragg gratings (CFBG). A novel demodulation of CFBGs based on optical power measurement is presented in the paper to replace traditional demodulation based on optical spectrum analyzer (OSA). The method uses two CFBGs of which the reflection spectra partially overlap each other. The wavelength shift of CFBG can be related to the optical power of overlap spectra of the two CFBGs. Therefore, the demodulation of CFBG can be realized by optical power measurement. The advantages of the demodulation method include simple structure, high flexibility, and low cost.
