Abstract :
Summary from only given. We have reported a simple scheme to suppress the SMN in dispersion-tuned, harmonically mode locked fiber ring lasers (DTHMLFRL) by introducing a semiconductor optical amplifier (SOA) into the ring cavity. Biased at its low-gain regime, the SOA suppressed the supermode noise (SMN) by 13 dB. Smooth wavelength tuning was achieved within 10 nm by varying the modulation frequency 0.25 MHz. 5.3-ps pulses were obtained at a repetition rate of 10 GHz. In this paper, we report the experimental study of this system at different driving currents of the SOA and compare some of the experimental data with result from numerical simulations.
