摘要
We numerically demonstrate a wavelength-tunable graphene-based mode-locked fiber laser with net anomalous cavity group-velocity dispersion. It is shown that by utilizing fiber birefringence, the central wavelength of mode-locked pulses could be continuously tuned over the range from 1553 to 1566 nm. The numerical results are in agreement with the experimental observations in the literature. The mechanism of wavelength tuning may be attributed to an artificial fiber birefringence-induced filter in the cavity.
