Abstract
A hybrid amplifier spanning from 1468 to 1568Â nm is constructed by cascading a thulium-doped fiber amplifier pumped at 690 and 1400Â nm and a Cerium co-doped high concentration wideband erbium-doped fiber amplifier. Results show seamless small signal net gain of 10Â dB and noise figure maintained below 10Â dB over the 100-nm gain bandwidth, making the amplifier a promising candidate for coarse wavelength division multiplexing in Metropolitan Area and optical access networks.
