摘要:

利用电磁感应透明实现弱光场条件下的强非线性效应,开辟了一个崭新的非线性光学研究领域—“弱光非线性光学”。主要介绍了基于电磁感应透明的Kerr非线性和四波混频效应。Kerr非线性在全光学开关、全光学逻辑运算和光量子逻辑门等方面有着潜在的应用价值。四波混频也具有非常广泛的应用,其中最重要的是把可调谐相干光源的频率范围扩展到红外和紫外。在简并情况下,四波混频对于自适应光学中的波前再现是很有用的。另外,在材料研究中共振四波混频技术是强有力的光谱分析工具。

Abstract:

It is important to obtain strong nonlinearities under the conditions of the weak-light through electromagnetically induced transparency (EIT), which opens up a new field about optical nonlinearities, named as weak-light nonlinearity. Kerr nonlinearities and four-wave mixing based on electromagnetically induced transparency are introduced. Kerr nonlinearities may be used on the all-optical switches and all-optical logical arithmetic and optical quantum logical gate and so on. Four-wave mixing effects also have many applications. The most important application is that it can expand the frequency of coherent light to infrared and ultraviolet spectrum. In the case of the degeneration, four-wave mixing effects are useful for wavefront reconstruction in the adaptive optics. Besides, in material research, the resonant four-wave mixing technique is a vigorous spectrum analyzing tool.

Key words: nonlinear optics, weak-light nonlinearity, electromagnetically induced transparency, Kerr nonlinearity, four-wave mixing
