%X In this paper, we propose a multiwavelength erbium-doped fiber laser (MW-EDFL). The configuration of the MW-EDFL consists of several linear Fabry¨CPerot (FP) cavities and a master-oscillation-power-amplifier (MOPA). These linear FP cavities are partially overlapped and include several sections of EDFs, fiber Bragg gratings (FBGs), and a fiber loop mirror (FLM). In our design, a low cost broadband FLM and six narrowband FBGs were used to obtain a stable six-wavelength fiber laser at room temperature. Using a section of EDF as an MOPA near the output end, the output power of the MW-EDFL is promoted. The characteristics of the MW-EDFL were also simulated by the OptiAmplifier software tool. The results of simulations and experiments match each other very well. The optimizing EDF length of the MOPA is about 1.5 m and the MOPA gains are about 4 dB to 7.5 dB. The linewidth, wavelength drift, and power fluctuation of the MW-EDFL are about 450 kHz, 0.05 nm, and 0.4 dB, respectively.
