  • Abstract
    A new design of a Nd-doped fluoride fibre for 1300 nm small-signal amplification is presented. By placing the active material so that the 1050 nm amplified spontaneous emission is discriminated, a gain improvement of up to 6.6 dB is predicted. By including higher order pump modes an extra 2.1 dB gain improvement is achieved.
