Abstract
A new structured dual-wavelength distributed feedback fiber laser is proposed. In this new structure, phase shift is introduced as well as equivalent phase shift. Theoretical analysis and simulation demonstrates this new structure is able to provide separate resonant cavities to overcome mode competition. Different channels of sampled fiber Bragg gratings are utilized simultaneously, so wide wavelength spacing could be achieved. A 31 GHz spaced dual-wavelength DFB fiber laser is achieved on an Er-doped fiber with excimer laser and homogeneous phase plate. Experiments shows that dual-wavelength lasing is achieved and laser power is in reverse proportion with coupling coefficient of the FBG.
Keywords: distributed feedback; dual-wavelength fiber laser; fiber Bragg Grating; equivalent phase shift
