| Abstract: | A new type of dual-wavelength linear cavity fiber laser based on the superimposed fiber grating and chirp fiber Bragg grating (CFBG) is proposed.The fiber laser adopts the superimp osed fiber grating whose reflectivity is above 99% and the chirp grating whose reflectivity has sunk place for wavelength selectio n,and the erbium-doped fiber is used for the gain medium.Based on gain equalization technology,by adjusting the weights on two ends of CFBG,the gain and loss are equal at two wavelengths in the cavity,so as to suppress mode comp etition and realize double wavelengths lasering at room temperature.The experimental results show that th e laser can output stable 1556.852nm and 1557.680nm dual-wavelength lasers at the same ti me,the line width is less than 0.1nm,side mode suppression ratio (SMSR) of the output laser reaches 15dB,and the stabilities of wavelength and power are very good.The laser coupling loss is small,structure is simple,integration is convenient,so it can be widely used in dense wavelength division multiplexing ( DWDM) system and optical fiber sensors. |
