We demonstrate a multiwavelength 10GHz pulse source using a dispersion-tuned actively mode-locked fiber ring laser incorporated with a semiconductor optical amplifier and an erbium-doped fiber amplifier. Simultaneous seven-wavelength operation of the laser is obtained. The side-mode suppression of all wavelengths is above 30dB. Smooth wavelength tuning is achieved over more than 12nm by changing the...
