摘要
A novel configuration of the tunable fiber laser with uniform wavelength spacing in dense wavelength division multiplexing （DWDM） application is proposed. The ring type tunable fiber laser consists of an all-fiber comb filter which determines the wavelength spacing, and a piece of adjustable fiber grating to select the discrete lasing wavelength for DWDM application. The proposed all-fiber ring type tunable laser has potential application in the DWDM and other optical systems due to its advantages such as narrow linewidth, easv tuning, uniform wavelength interval, etc..
