چکیده انگلیسی
In this paper, we propose and experimentally demonstrate a C- and L-band erbium-doped fiber laser (EDFL) with tunable single-, dual- and triple-wavelength lasing emissions. A tapered structure large-core fiber filter (LCFF) is inserted to serve as tuning component and wavelength selector for tunable and stable multi-wavelength oscillations. Based on the axial strain response of LCFF, two tunable triple-wavelength regimes within the range from 1558.71 to 1579.81â¯nm are obtained with side mode suppression ratio (SMSR) as high as 55â¯dB. Moreover, tunable single- and dual-wavelength regimes are also achieved with total tuning range of 11â¯nm and 6.23â¯nm, respectively. The tuning step for overall laser regimes is 0.02â¯nm, and the maximum wavelength sensitivity reaches to 1.87â¯pm/με. In addition, this proposed versatile EDFL is proved to be very stable since the lasing wavelength shifts and power fluctuations are less than 0.02â¯nm and 0.78â¯dB during an hour.
