Erbium-doped Fiber Laser with Distributed Feedback from a Fiber Grating Array

An erbium-doped fiber laser with low coherence, low threshold, high efficiency and narrow linewidth is demonstrated for the first time based on distributed feedback from a fiber Bragg grating (FBG) array. The FBG array contains tens of FBGs with identical Bragg wavelength but very weak reflectivity...
