Abstract
We present the transfer matrix based analysis of the distributed feedback (DFB) fiber laser with an extra weak optical feedback introduced by a fiber end facet directly. The lasing frequency and output power could be modulated by the modulation of the weak feedback parameters, including the phase and intensity of the feedback light. A corresponding simple intensity based DFB fiber laser vibrometer is proposed according to the analysis and the experimental results are given to prove it feasibility. With the advantages of simple and compact structure, the sensing scheme is expected to have broad applications.
