A multiwavelength fiber laser based on erbium-doped twin-core fiber (ED-TCF) and nonlinear optical loop mirror (NOLM) is proposed and demonstrated in this paper. The ED-TCF is employed as comb filter and gain medium simultaneously. The NOLM serves as an intensity equalizer. A fiber laser with 8 wavelength outputs is achieved at room temperature. The optical signal to noise ratio (OSNR) is larger than 40 dB. The fluctuation of peak power and wavelength is less than 1 dB and within 0.015 nm, respectively. This fiber laser has the advantages of simple structure and stable operation.
