Paper Abstract

We investigate an ultra-weak feedback effect of DBR fiber lasers based on the steady-state rate equations. The ultra-weak-feedback effects of DBR fiber lasers are introduced by the fiber Rayleigh scattering and the scattering of the fiber splicing point. The output powers of the DBR fiber lasers are modulated when their feedbacks are modulated. A simple vibration sensing scheme based on this effect is proposed and demonstrated. The optimized design of the sensing scheme is discussed at last.
