We propose and experimentally demonstrate a multiwavelength erbium‐doped fiber ring laser using a fiber Sagnac loop filter. The fiber Sagnac loop filter served as the wavelength selection component within the ring laser cavity. By carefully tuning the setting of the polarization controller (PC) to effectively change the state of polarization of the light, three, four, and five lasing wavelengths were obtained from the output port of the ring laser. The proposed multiwavelength ring laser has the unique advantages of simple structure, changeable wavelength spacing, tunable number of lasing lines, and low cost. © 2008 Wiley Periodicals, Inc.
