A discretely tunable Er‐doped fiber‐ring laser using a fiber Mach‐Zehnder interferometer (MZI) and a tunable fiber Bragg grating (FBG) is proposed. In this scheme, the combination of MZI and FBG acts as a discrete wavelength selector. Analysis of its transmission function shows that discrete wavelength tuning can be realized, and experiments demonstrate 64 single‐mode outputs with a mode spacing of 181.7 pm, and the output power is quite stable in the whole tuning range. © 2009 Wiley Periodicals, Inc.
