摘要

In the twentieth century,revolutionary changes took place in the human society and people\''s life-style due to the improvement of the optoelectronic information technology based on the second-order nonlinear optical effects,such as the electro-optic effect,the second harmonic generation(SHG),and so on.Along with the rapid development of light information technology,new principles and methods of nonlinear optics are needed,and the third-order nonlinear optical effects attract great attention.The research progress of nonlinear optics is reviewed in this article.Our research work on the third-order nonlinear optical materials,ultrafast and low-power organic all-optical photonic crystal switching are introduced.
