本文综述了类二苯乙烯偶氮苯的三阶非线性性质，并展望了其在超快光信号处理中的应用。我们讨论了负责偶氮苯的非线性响应的机制。通过综合文献中报道的实验数据和理论趋势，我们确定了光学非线性响应的五个特征区域。相对于Stegeman品质因数分析，伪芪型偶氮苯显示出在两个光谱区域中的超快光信号处理的前景，一个位于主和双光子吸收共振之间，另一个波长长于双光子吸收共振。(C)2001 Kluwer Academic Publishers.
We review the third-order nonlinear performance of pseudo-stilbene type azobenzenes with an eye to application in ultrafast optical signal processing. We discuss mechanisms responsible for the nonlinear response of the azobenzenes. By aggregating experimental data and theoretical trends reported in the literature, we identify five characteristic regions of optical nonlinear response. Analyzed with respect to Stegeman figures of merit, pseudo-stilbene type azobenzenes show promise for ultrafast optical signal processing in two spectral regions, one lying between the main and two-photon absorption resonances, and the other for wavelengths longer than the two-photon absorption resonance.
