A stable and narrow wavelength spacing multiwavelength erbium-doped fiber laser is proposed and demonstrated. The laser can produce simultaneous dual- and triple-wavelength lasing oscillations with a narrow wavelength spacing of less than 0.1nm via using a single fiber Bragg gratings written in polarization-maintaining (PM) fiber. By adjusting polarization controller, the wavelength spacing of dual-wavelength...
A novel independent tuning technology for center wavelength and bandwidth of fiber Bragg grating was demonstrated. A fiber Bragg grating was bonded to the side surface of elastic column beam with a determinate angle along its axial direction. Center wavelength and bandwidth of the fiber grating can be tuned through changing torsional angle and lateral displacement of the beam, respectively. Quasi-chirp-free...
