چکیده انگلیسی
In this paper, a tunable single-wavelength erbium-doped fiber ring laser is proposed. A novel fiber filter based on a large-core fiber is developed for suppressing the mode competition in erbium-doped fiber lasers (EDFLs). Under the pump power of 250â¯mW, single-wavelength lasing output is implemented with a side mode suppression ratio (SMSR) higher than 55â¯dB. By adjusting the curvature applied on the large-core fiber, stably tunable single-wavelength lasing output within the wavelength range from 1552.4â¯nm to 1563.2â¯nm is obtained with a 3â¯dB linewidth of 0.2â¯nm. Furthermore, the wavelength shift and peak power fluctuation are controlled within 0.02â¯nm and 0.5â¯dB by monitoring the lasing output with an interval of 6â¯min in one hour, respectively. A contrast experiment of a laser without tapering LCF is carried out to examine the importance of the taper in LCF-based filter. Experimental results demonstrate that the side modes of the lasing output can be effectively suppressed and thus SMSR can be improved from 41â¯dB to 58â¯dB by using a taper.
