摘要:

本文描述了一种新的双模系统,它由类克尔介质和下转换过程组成,称为克尔下转换系统。在一定的条件下,我们可以得到动力学方程的精确解。对于这个系统,我们研究了不同类型的正交压缩,例如,单模、双模和压缩。同时给出了主压缩的更一般的定义。我们发现,由克尔样和下转换过程分别产生的非经典效应的量大于从克尔下转换系统,其中两个过程是在竞争中获得的。

英文摘要:

In this Letter we describe a new two-mode system, which consists of Kerr-like medium and down conversion process, called the Kerr-down conversion system. Under a certain condition we can obtain an exact solution of the dynamical equations of motion. For this system we investigate different kinds of quadrature squeezing, e.g., single-mode, two-mode and sum-squeezing. Also we give a more general definition of the principal squeezing. We show that the amounts of nonclassical effects produced by the Kerr-like and down-conversion processes separately are greater than those obtained from the Kerr-down conversion system where both the processes are in competition.
