Abstract(in English) We demonstrate a wide and fast wavelength-tunable mode-locked fiber laser based on tuning the mode-locking frequency. The laser is a sigma-laser configuration and a wideband semiconductor optical amplifier (SOA) at 1.3μm is used as a gain medium. Mode-locking is achieved by direct modulation of the injection current to the SOA, and a dispersion compensation fiber (DCF) is used to provide the desired intracavity dispersion. By tuning the modulation frequency, a wide tuning range over 90nm was achieved. Lasing wavelength was measured to be in linear proportion to the RF frequency applied to the SOA. The sweep rate over the entire wavelength range (90nm) could be raised to be as high as 20kHz.
