Abstract :
A tunable dual-wavelength erbium-doped fiber laser (EDFL) is proposed and demonstrated. By applying axial and lateral strain simultaneously on the fiber Bragg grating (FBG), the absolute wavelength and wavelength spacing of the EDFL can be tuned continuously. The FBG used included not only the FBG fabricated in standard single-mode fiber, but also the FBG in polarization-maintaining fiber. The experiment results are similar.
