• Tunable DBR fiber laser
• Closed-loop
• PZT

A linearity tunable fiber laser based on closed-loop piezoelectric ceramics (PZT) is proposed and successfully demonstrated. The cavity of the distributed Bragg reflector (DBR) fiber laser is fixed on the PZT, and the displacement sensor attached on the PZT is monitoring and compensating the nonlinear hysteresis of the PZT real-timely. Experimental results show that the tuning curve of the DBR fiber laser is linear with the tuning range nearly 0.8 nm. Furthermore, the automatic tuning DBR fiber laser driven by the sawtooth wave is realized in closed-loop PZT operation.
