| 摘 要： | 利用置于光腔中的非线性耦合器制备了压缩和连续变量纠缠光.通过特征函数方法解析求解了双模腔场满足的主方程.分析发现：在一定的条件下,此系统能产生稳定的双模压缩和连续变量纠缠光,且压缩和纠缠的强度与系统的耦合参量及腔场损耗系数密切相关.

| Abstract: | The generation of two-mode squeezed and entangled light in a nonlinear coupler inside an optical cavity was studied.The master equation of the two-mode field was solved by the method of characteristic function.It shows that the state of the two-mode field is a two-mode Gaussian one,and under some conditions,the two-mode cavity field exhibits stable two-mode squeezing and continuous variable entanglement.The degree of the squeezing and entanglement is dependent on the damping rate of the cavity field and the coupling constants between the two modes. |
