In this paper, a figure-8 laser based on a semiconductor optical amplifier (SOA) for generating dark pulses is proposed. By adjusting the polarization controller, dark pulses with repetition frequency from 9.10 to 33.44 MHz are generated. The pulse widths are from 74.26 to 19.96 ns. The laser consists of an SOA asymmetrically placed in a short fiber loop. Its switching time is determined by the off-center position of the nonlinear element within the loop. Pulses transmitting in the clockwise and counterclockwise directions have the same widths. Then, the two pulses with the same widths overly together and form the dark pulse.
