We demonstrate a dual-stage gain-clamped erbium-doped fiber amplifier. The first-stage amplifier consists of a short length of erbium-doped fiber to produce low noise figures. The second-stage is constructed from a counter-propagating ring-laser, in which the signals and the lasing wavelength propag
A gain-clamped erbium-doped fiber amplifier EDFA is demonstrated using a double-pass superfluorescent laser centered in the 1530 nm band. The gain is clamped at 21 dB with about 0.2 dB ¨ariation, and the gain flatness between channels is kept below 0.6 dB o¨er 11 dB of input signal power ¨ariation.
## Abstract A new design of an allβoptical gainβclamped erbiumβdoped fiber amplifier is demonstrated. The amplifier is based on the conventional ring cavity, where the gain is clamped at 21.84 dB via optical feedback using a single fiber Bragg grating for an input signal power as high as β8 dBm.βΒ©
