Abstract
Distributed feedback fiber lasers with multiple phase shifts are fabricated and investigated. Single longitudinal mode lasers with single polarization are obtained by the structure design with two phase shifts. No obvious differences in laser performance, including pump threshold, slope efficiency, relative intensity noise, spectral linewidth, and polarization state, are observed for the presented distributed feedback fiber laser structures with different phase shift locations.
