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 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 pow
relocated from 1.86 to 1.97 GHz whilst the upper zero varies from 2.24 to 2.04 GHz. ## 3. MEASURED RESULTS To verify the proposed approach, a filter is designed at f 0 ฯญ 2 GHz with 3.5% FBW and R ฯญ 0.64 using the dimensions as reported in the last section. The substrate used is RO4003 with relativ
