Abstract
This paper present a gain-clamped L-band EDFA based on reflecting back a portion of backward amplified spontaneous emission into the erbium-doped fiber section, utilizing a fiber Bra99 grating. By using FBG with R=66.1 and 99.9%, the gain is clamped at 15.1 and 14.3㏈, respectively, with a variation of less than 0.2㏈ for an input signal power as high as -5 ㏈m. However, a small noise figure penalty is obtained, which is the consequence of the gain clamping effect.
