Multi wavelength Laser Utilizing Fabry-Pérot Interferometer in Hybrid Raman and Erbium Doped Fiber Gains

This paper demonstrates and discusses a generation of multi wavelength Laser Utilizing Fabry-Pérot Filter in Hybrid Raman and Erbium Doped Fiber Gains has been proposed and investigated experimentally. The Hybrid Raman-Erbium Doped Fiber (EDF) gain produce the stability of the ring cavity laser at room temperature. A Fabry-Pérot (F-P) Filter as a comb filter and a Gain Flattening filter form a resonant cavity is producing a stable Multi wavelength output. The key features of multi wavelength laser are high Side-Mode Suppression Ratio (SMSR), smaller Free Spectral Range (FSR), and narrow line width had been discussed about and studied.
