| Abstract(in English) | We demonstrate a stable and ultra-wideband wavelength-tunable actively mode-locked short-cavity fiber ring laser employing a 151-cm-long bismuth-oxide-based highly nonlinear erbium-doped fiber (Bi-HNL-EDF). Since the Bi-HNL-EDF has an ultra-wide gain bandwidth covering both the C-band and the L-band, an 87-nm wavelength tuning from 1533nm to 1620nm can be achieved. The supermode noise can also be suppressed effectively because the Bi-HNL-EDF has a high nonlinear coefficient γ of 50W^<-1>km^<-1>. The total cavity length is as short as 8m because of the short length of the Bi-HNL-EDF, resulting in better stability against external perturbation. Thus, stable and clean short pulses with a repetition rate of 10GHz can be successfully generated over the entire wavelength tuning range. |
