Paper Abstract

A 16 channel distributed feedback fiber laser sensor array is reported. The spacing of neighbor lasers is 100 GHz and 200 GHz in turn. Compared with grating sideband reflection, Rayleigh backscattering from ~24 m long passive fiber is more responsible for the instability, and it's found that increasing the reflection of grating could reduce the sensitivity of DFB FL to Rayleigh backscattering.
