A multi-wavelength erbium-doped fiber laser incorporating an semiconductor optical amplifier (SOA) based on a tunable Mach-Zehnder interferometer (as a comb filter) is proposed. Wavelength-spacing can be continuously tuned and multi-wavelength lasing with wavelength spacings of 0.4 nm, 0.8 nm, and 1
