摘　　要：Wavelength-tunable dissipative solitons and amplifier similaritons have been obtained by inserting all-fiber Mach-Zehnder interferometer(MZI) filters with different free spectral ranges(FSRs) in a Yb-doped mode-locked fiber laser.The MZI filter is fabricated by splicing one segment of seven-core fiber(SCF) between two segments of single-mode fibers.The bandwidth of the filter depends on the FSR of the modulated interference curve and consequently depends on the tapered fiber diameter.Inserting MZI filters with bandwidths in a fiber laser and applying a tensile strain on the tapered SCF,both wavelengthtunable dissipative solitons and amplifier similaritons have been obtained.
