Abstract
A simple multiwavelength Raman fiber ring laser with equalized peak power is proposed and demonstrated experimentally by inserting a sample chirped fiber Bragg grating. By adjusting the polarization controller (PC) in the ring cavity, up to ten stable wavelengths with equalized peak power are achieved at room temperature. The Raman fiber ring laser has many advantages such as simple structure, low loss, and multiwavelength lines with moderate output power. Β© 2007 Wiley Periodicals, Inc.

We theoretically investigated the two methods for densifying the channel spacing of sampled fiber Bragg gratings (SFBGs), the multiple-phase-shift (MPS) method and the linear chirp method, and found that the two methods have similar principle and ability, although the chirp method has an advantage t
## Abstract A reconfigurable multiwavelength erbiumβdoped fiber laser, using two multimode fiber Bragg gratings (MFBGs), is presented. Two MFBGs in Lβband are cascaded to form two overlapping resonant cavities. Various configurations of fourβ, threeβ, or twoβwavelength lasing are demonstrated exper
