概要
- 論文の詳細を見る
We theoretically explain the power saturation and the additional phase noise brought by the fiber optical parametric amplifier (FOPA). An approximated result to calculate the saturated signal output power is presented. We also propose a scheme for alleviating the phase noise brought by the signal itself at the saturated state. From simulation, it was found that by controlling the decisive factor dispersion difference term Δk of the FOPA, amplitude-noise and additional phase noise reduction of quadrature phase shift keying (QPSK) based on the saturated FOPA is studied, which can provide promising performance to deal with PSK signals.
