Abstract
A novel electrically tunable fiber Bragg grating (FBG) laser is reported. The FBG can be coupled to the fiber efficiently. The FBG is pasted on the surface os a magnetostrictive rod. The magnetostrictive rod is placed in a solenoid and it stretches under a magnetic field. Then the FBG is tuned, and the laser's wavelength alters. The tuning range is 1.6nm, the line-width is narrower than 0.3nm.
