A narrow-linewidth, tunable, dual-wavelength fiber laser operating at room temperature with each lasing wavelength in single-longitudinal-mode operation is demonstrated. A commercially available tunable fiber Bragg grating was used to tune one of the lasing lines. An unpumped elliptical-core erbium-doped fiber was used as a saturable absorber to suppress mode hopping. Wavelength switching was achieved using a polarization controller. The linewidth (FWHM, full width at half maximum) of the laser line was 6.7 MHz and the OSNR (optical signal to noise ratio) was more than 40 dB.
