In order to develop both cheap and stable ultra-broadband light sources,the output spectral characteristics of ultra-broadband light source based on Bismuth-Erbium co-doped fiber(BEDF)are investigated.With the 830 nm lasers as pump,the output spectrum covers the whole O-,E-,S-,C-,L-bands and the full width at half maximum(FWHM)reaches 525 nm.With the application of BEDF ultra-broadband light source in wavelength division multiplexing fiber Bragg grating(FBG)sensing system,the strain sensing at O band and C ...
