Impairments in deeply-saturated optical parametric amplifiers for amplitude- and phase-modulated signals.
We measure impairment of on-off-keyed and differential-phase-shift-keyed signals imposed by gain saturation in a fiber parametric amplifier. Phase modulation is observed to be more robust, particularly for deep (15 dB) saturation.
