Multiwavelength comb generation in an all‐fiber self‐starting passively mode‐locked figure‐eight erbium‐doped fiber laser is experimentally demonstrated. The nonlinear optical‐loop mirror (NOLM) consisting of a symmetrical optical coupler and a length of single‐mode fiber can act as the mode‐locking element through nonlinear polarization rotation. The linear ring with a section of polarization‐maintenance fiber and a polarization‐dependent isolator can implement linear filtering. Such a self‐starting passively mode‐locked erbium‐doped fiber laser can generate pulses with multiwavelength comb, which is characteristic of all‐fiber and simple configuration. © 2006 Wiley Periodicals, Inc.
