Abstract
We demonstrate a single-frequency wavelength tunable erbium-doped fiber (EDF) ring laser. We used an unpumped-EDF as a saturable-absorber in order to obtain a stable single-frequency with a narrow-linewidth single-polarization mode in the ring cavity. The lasing wavelength was controlled by using bending-induced strain, such as tension and compression strain corresponding to the bending direction, applied to the fiber gratings. The fiber laser exhibited an output power of -1.85 dBm at a wavelength of 1540.72 nm for a pumping power of ~400 mW. An extinction ratio was measured to be more than 60 dB. The proposed tunable fiber laser maintains nearly the same output power while its lasing wavelength is controlled over in a wavelength range of 5 nm.
