Multiple Wavelength Laser Source Generation Using a Bismuth-Based Erbium-Doped Fiber in a Linear Cavity

A compacted optical amplifier is demonstrated for multi-wavelength laser source generation in a linear cavity. A 25 km single mode fiber (SMF) is used as the non-linear Brillouin gain medium for the generation of Brillouin Stokes whereas a 2.15 m of Bismuth-based Erbium doped fiber (Bi-EDF) is used to yield Bi-EDF optical amplifier for the cascaded multi-wavelength generation. Unlike conventional multi-wavelength Brillouin/Erbium fiber laser systems, Brillouin pump seed wavelength is near but out of the free-running Bi-EDFA wavelength region. However, the number of the lines is about 20 more due to using simultaneously Raman and EDF amplification.
