四波混频（FWM）现象的新实验研究包括将三个光波（泵浦、探测和测试）发射到半导体光放大器中，测量测试光束的透射率和测试光束一侧产生的新光波的转换效率。它允许一个很好的识别的非线性现象中所涉及的四波混频过程。的分析原理是基于调制的增益曲线的三种效果考虑：光谱烧孔，载流子加热，载流子密度脉动。实验和理论结果。
The new experimental research on the four-wave mixing (FWM) phenomena described here consists in launching three optical waves (pump, probe, and test) into a semiconductor optical amplifier and measuring the test beam transmission and the conversion efficiency of the new wave generated to one side of the test beam. It allows for an excellent identification of the nonlinear phenomena involved in the FWM process. The analysis principle is based on the modulation of the gain curve for each of the three effects considered: spectral hole burning, carrier heating, and carrier density pulsation. Experimental and theoretical results are presented.
