## Abstract A new design of an all‐optical gain‐clamped erbium‐doped 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 −8 dBm. ©
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
## Abstract The use of dual‐stage gain‐clamped erbium‐doped fiber amplifier (GC–EDFA) having a pump laser diode and 16‐channel wavelength‐division multiplexing (WDM) of 0.8 nm spacing in the C‐band of 1545–1560 nm wavelength was demonstrated in a burst packet‐mode optical switching system through a
