A new demodulation method of fiber Bragg grating (FBG) sensing signal, which is by making use of the monotonic decline section of an amplified spontaneous emission (ASE) light source, is proposed.

The spectrum of ASE broadband light source was measured by FFTS system, and the experiment result agrees with that tested by grating spectrometer.
A novel two-stage Er-doped ase broadband light source with two output bands, i. e. C-band and L-band was designed and demonstrated based on the analysis of the principle of the L-band ase spectrum.
