  • Abstract
    A new Er-doped fibre design for low noise amplifier applications is presented. The active fibre is continuously uptapered from the signal input end to the signal output end. Generated amplified spontaneous emission is thus reduced and high gain properties are preserved. Noise figure reductions of more than 0.5 dB for copropagating pump and 2.0 dB for counterpropagating pump are predicted.
