研究表明，腔内克尔非线性耦合器是一种潜在的连续可调谐、空间分离的明亮纠缠光束源。我们使用线性波动分析来计算必要的相关性，在政权，它是有效的。这意味着我们正在处理系统呈现高斯统计的制度，以便众所周知的标准既必要又足以证明纠缠。该系统可以用集成光学器件来实现，因此提供了一种潜在的坚固和稳定的明亮纠缠光束源。
We show that the intracavity Kerr nonlinear coupler is a potential source of bright continuous variable entangled light beams which are tunable and spatially separated. We use a linearized fluctuation analysis to calculate the necessary correlations in regimes where it is valid. This means that we are treating regimes where the system exhibits Gaussian statistics so that well-known criteria are both necessary and sufficient to demonstrate entanglement. This system may be realized with integrated optics and thus provides a potentially rugged and stable source of bright entangled beams.
