## Abstract A simple microwave signal source is proposed by connecting two single‐longitudinal‐mode erbium‐doped distributed Bragg reflector fiber lasers in series. For using same pump LD, mutual injection locking of two fiber lasers is achieved. The two single‐longitudinal‐mode lasers have 0.048 n

## Abstract An active strain sensing system based on single‐longitudinal‐mode distributed Bragg reflector fiber laser is proposed and experimentally demonstrated. Owing to the short laser cavity length and birefringence‐induced mode splitting, the proposed laser in single‐longitudinal‐mode operatio
