非线性光学中为什么不能用电场来解释
Why you should not use the electric field to quantize in nonlinear optics
摘要：
我们发现，使用电场作为非线性光学中的量子化变量导致不正确的表达式的压缩参数的自发参量下转换和频率转换的转换率。这一观察结果与这样一个事实有关，即如果电场被写为玻色子产生和湮灭算子的线性组合，则在非线性电介质中不能满足麦克斯韦方程。
英文摘要：
We show that using the electric field as a quantization variable in nonlinear optics leads to incorrect expressions for the squeezing parameters in spontaneous parametric down-conversion and conversion rates in frequency conversion. This observation is related to the fact that if the electric field is written as a linear combination of bosonic creation and annihilation operators one cannot satisfy Maxwell's equations in a nonlinear dielectric.
