Abstract :
We show that a saturated semiconductor optical amplifier reduces the amplitude noise of phase-coded signals without adding excess phase noise in presence of an additional CW beam with proper power. Pass-through and four-wave-mixing converted signals exhibit significant improvement of the BER threshold margin for 10 Gb/s NRZ DPSK data.
