Abstract

A Sagnac interferometer has been used in the ring cavity to produce a multiwavelength fiber laser. The results show that an elliptical‐core erbium‐doped fiber can produce more stable lasing lines compared to a normal erbium‐doped fiber. The principle of operation is based on polarization‐dependent gain phenomena in erbium‐doped fiber. The number of lasing lines and stability may be adjusted by using a polarization controller to control the polarization of the wave inside the cavity. © 2003 Wiley Periodicals, Inc.

In this letter, we propose a novel multiwavelength fiber laser based on fiber loop mirror formed by a high-birefringence fiber, a polarisation controller, and a 3 dB directional coupler. By setting the polarisation controller as half-wave-plate, the fiber loop mirror acts as a polarisation-independe
