| Abstract: | A new method of tuning fiber Bragg gratings(FBGs)is described, in which FBGs were metallized and the electric thermal effect of the metal film was used to tune the FBGs by temperature. The method has advantages of simplicity, easy to use, small size, high tuning speed and easy to be integrated with circuits. When the applied current increased from 0 mA to 180 mA, the Bragg wavelength of the fiber grating increased from 1553.14 nm to 1555.48 nm with tuning range of 2.34 nm. The rise time of tuning was measured to be around 20 ms. Some experimental results are discussed in the paper. |
