چکیده انگلیسی
A stable and widely tunable single-/dual-wavelength erbium-doped fiber laser (EDFL) is proposed by cascading a homemade twin-core photonic crystal fiber (TCPCF) based filter with Mach-Zehnder interferometer (MZI). By bending the TCPCF, single-wavelength lasing can be tuned from 1560.4â¯nm to 1583.44â¯nm with the tuning step of â¼0.78â¯nm and the widely tunable wavelength range over 23.04â¯nm can be achieved. Furthermore, by adjusting polarization controller, the output lasing can be switched from single-wavelength to dual-wavelength; the dual-wavelength lasing with wavelength interval of 0.78â¯nm can be tuned over a range of 33.82â¯nm from 1559.72â¯nm/1560.48â¯nm to 1593.54â¯nm/1594.32â¯nm. The tuning step and the interval of dual-wavelength is determined by the MZI. The SMSR of single- and dual-wavelength are higher than 45â¯dB and 42â¯dB, respectively. In addition, the stability of output lasing is measured experimentally. Excremental results demonstrate that the wavelength drift is less than 0.02â¯nm and peak power fluctuations of single-/dual-wavelengths are less than 0.47â¯dB and 0.8â¯dB, respectively. Such wide tuning range, small wavelength drift and high power stability makes this tunable EDFL have a potential application in the fields of optical fiber communication and sensing.
