Abstract

A dual-wavelength single-longitudinal-mode erbium-doped fiber ring laser, comprising an inverse- Gaussian apodized fiber Bragg grating (IGAFBG) with two passbands and a saturable absorber, is proposed. The wavelength spacing between the two lasing lines can be continuously tuned by changing the wavelength spacing of the two passbands of the IGAFBG, which can be realized by adding a tunable linear chirp in the grating using a cantilever. By heterodyning the two lasing lines at a photodetector, a microwave signal with a tunable frequency is achieved.
