Multi‐wavelength L‐band gain‐clamped erbium‐doped fiber amplifier with high gain and flatness by using composite FBGS

Abstract: The gain‐clamped erbium‐doped fiber amplifiers (EDFA) can efficiently stabilize the gain fluctuation of signals, but with the price of gain–loss and worsened flatness. In this paper, we theoretically study the relationships between clamping and loss and propose a novel linear‐cavity gain controller based on a pair of composite fiber Bragg gratings (FBGs) to balance gain and clamping, which consist of a uniform FBG with high‐reflectivity and a chirp‐FBG with low‐reflectivity. The comprehensive experiments and c… Show more
