摘      要：正 A novel configuration to implement the tunable fiber laser with uniform wavelength spacing for DWDM application is proposed in this paper. The ring type tunable fiber laser consists of an all fiber comb filter used to determine the wavelength spacing, and a piece of fiber grating adjustable to select the discrete lasing wavelength for DWDM application. The all fiber ring type tunable laser posses the advantages of narrow linewidth, easy tuning, uniform wavelength interval, etc. The proposed tunable fiber laser has potential application in the DWDM and other optical systems.
