Abstract
Two effects of noise in saturated semiconductor optical amplifiers used in all-optical signal processing are described. The nonlinear coupling between the injected signal and the spontaneous emissions causes significant reduction in the narrow-band intensity noise power relative to the level predicted in linear amplifiers with the same gain. The second is an increase in the amplified spontaneous emission power of a saturated amplifier due to the longitudinal dependence of the carrier density in nonlinear amplification.
