论文摘要
我们提出了一种一般方法，以建模一种基于耦合的谐振器光学波导的反向传播的综合源源，该态被从波导上方泵送的经典脉冲源泵送。本文是我们以前的工作〜（参考\ cite {physReva.100.033839}）的扩展，在此，我们分析研究了在本质上损失的情况下，在这个耦合的狂热系统中，在这种耦合狂热系统中，继续变化的纠缠状态的产生和传播。但是，在这项工作中，我们采用了一种数值方法来实施Schmidt分解方法，而不是采用分析方法。我们表明，这不仅使我们在选择泵送参数方面具有更高的自由度，而泵送参数无法进行分析，而且还使我们能够超越以前得出分析表达式所做的一些近似值。
We present a general approach to model an integrated source of counterpropagating continuous-variable entangled states based on a coupled-resonator optical waveguide that is pumped by a classical pulsed source incident from above the waveguide. This paper is an extension of our previous work~(Ref. \cite{PhysRevA.100.033839}), where we analytically investigated the generation and propagation of continues-variable entangled states in this coupled-cavity system in the presence of intrinsic loss. However, in this work, we employ a numerical method to implement the Schmidt decomposition method rather than pursuing analytical methods. We show that not only this gives us a much higher degree of freedom in choosing the pumping parameters which were not possible to investigate analytically, but also it enables us to go beyond some of the approximations we had made to derive analytical expressions before.
