Abstract :
A measurement of carrier recovery time in semiconductor optical amplifiers (SOAs) based on dual pumps four-wave mixing (FWM) is presented. The results show the carrier time is 91 ps, 79 ps and 63 ps at 120 mA, 180 mA and 240 mA, respectively, which agree to our expectation. The experimental results show the conversion efficiency keeps constant when the spacing of the two pumps varies within a small range.
