Abstract

? phase-shifted distributed feedback fiber lasers , ofwhich the power would focus on the phase-shift region ifthe coupling coefficient was high enough, was often adopted in order to acquire single-frequency output. But if the phase shift region was far away from the center of the grating, the output wavelength would be different that the fundamental mode would focus on the port which was near the phase shift region while the ±1 modes would focus on the other port due to the spatial hole burning. Both the theoretical analysis and experiments were presented.
