| Abstract: | The application of stepping motor in fiber bragg grating external cavity semiconductor laser is analyzed in this paper. The angular displacement of stepping motor and controlling pulse are synchronous. The width and frequency of motor is supported by single chip. Connecting rod,wheel gear and other precision machinery make up of actuating mechanism which are linkedwith a micrometer The FBG is stretched by the micrometer. Then the wavelength tuning of external cavity semiconductor laser is realized through stepping motor. |
