Abstract: A programmable wavelength widely tunable Er-doped fiber laser is demonstrated. The tunable range can cover above 51nm (1516.8—1568.3nm) controlled by software and tunable step is up 0.01nm. The laser and fiber Bragg grating (FBG) make up quasi-distributed temperature sensing system, which is applied in power system to achieve real-time temperature of 16 fibers channels, a total of 48 monitoring points.
