四波混频可以被激发，也可以自发发生。第一个过程本质上要强得多，并通过经典的非线性光学得到了很好的理解。后者也被称为参数荧光，只能在光的量子理论框架下解释。我们的实验证明，在微环谐振器中，这两个过程的效率之间存在一个简单的关系，它与非线性和环的尺寸无关。特别是，我们已经证明了由参数荧光产生的平均功率可以立即从经典的四波混频实验中估计出来。这些结果表明，光子集成结构的经典非线性表征可以提供有关其非线性量子性质的准确信息。(C)2012年美国光学学会
Four-wave mixing (FWM) can be either stimulated or occur spontaneously. The first process is intrinsically much stronger and well understood through classical nonlinear optics. The latter, also known as parametric fluorescence, can be explained only in the framework of a quantum theory of light. We experimentally demonstrated that, in a microring resonator, there is a simple relation between the efficiencies of these two processes that is independent of the nonlinearity and ring size. In particular, we have shown the average power generated by parametric fluorescence can be immediately estimated from a classical FWM experiment. These results suggest that classical nonlinear characterization of a photonic integrated structure can provide accurate information on its nonlinear quantum properties.
