In this paper, a dual-wavelength fiber laser (DWFL) using nano-engineered Thulium-doped fiber as a gain medium with a bent singlemode-multimode-singlemode fiber structure (SMS) is demonstrated. The SMS structure is packaged systematically using Cr-39 polymer plates to provide linear bending via applied load. Experimental results have proved that the bent SMS is capable to provide highly effective wavelength filter and wavelengths stabilizer by balancing the net cavity gain between the two wavelengths. The DWFL provides very narrow spacing of 0.9 nm, narrow 3 dB spectral linewidth of similar to 0.07 nm and SNR of similar to 42 dB. Based on stability test, very small mode hopping is observed at the two wavelengths having deviations of +/- 0 nm and +/- 0.04 nm respectively. In conjunction, the DWFL provides very stable relative wavelength spacing with a deviation of +/- 0.04 nm. (C) 2016 Published by Elsevier Inc.
