| Abstract: | The application of stepmotor in the tuning fiber Bragg grating(FBG) external cavity semiconductor laser are analyzed.By using synchronization between the angular displacement of stepmotor and controlling pulse,the pulse width and frequency of the motor are supported by single chip.Connecting rod,wheel gear and other precision machinery make the mechanism actuated which are linked with a micrometer,by which the FBG is stretched.Then the wavelength tuning of external cavity semiconductor laser is realized through the stepmotor. |
