Fig. 1. Schematic diagram of the wavelength swept fiber laser based on dispersion tuning. WDM: wavelength-division multiplexer, ISO: optical isolator, OC: optical coupler.
Fig. 2. Spectra of single-wavelength operation at six modulation frequencies from 200.033 to 200.078 MHz.
Fig. 3. (a) The pulse train of a single-wavelength operation at the modulation frequency of 200.053 MHz. (b) The corresponding frequency spectrogram of the pulse train.
Fig. 4. The relationship between the output single wavelength and the modulation frequency change at three different mode-locking orders. The red lines are the linearly fitted lines of the experimental data.
Fig. 5. The static linewidth of seven wavelengths from 1023 to 1041 nm at three different mode-locking orders.
Fig. 6. The wavelength swept peak-hold spectra at three different sweeping rates of 50, 200, and 1000 Hz.
Fig. 7. The temporal sweep output at the sweeping rate of 50 Hz. The blue line is the sinusoidal sweep signal.
