Abstract
We present a wideband fiber amplifier with a flat gain spectrum ranging from 1306 to 1441 nm at a 3 dB level from maximum of 26 dB based on bismuth-doped active fibers with phosphosilicate and germanosilicate glass core. Combination of pumping at 1180 nm and gain clamping at 1280 nm was used to achieve a wider gain spectrum.
