| Abstract: | A new theoretical model is presented to investigate the amplification of strong ultrashort optical pulses in semiconductor optical amplifiers,while taking free-carrier Absorption,stimulated emission,two-photon Absorption,spectral hole burning and ultrafast nonlinear refraction into account.Based on this model,the pulsed four-wave mixing model is developed to further simulate the optical sampling based on four-wave mixing theory in semiconductor optical amplifiers.The influences of free-carrier Absorption and two-photon Absorption on sampling characteristics are emphasized.The simulation results are in agreement with reported experimental results. |
