论文摘要
可以使用自发参数下调（SPDC）来增强损失的微孔谐振器内部的强度积累。在这项工作中，我们在微孔谐振器中对挤压光的产生进行建模，该谐振器通过侧耦合通道波导泵送高斯脉冲。从理论上讲，我们确定最佳的泵脉冲持续时间和环向通道耦合常数，以最大程度地减少环中的正交噪声（最大化挤压），以获得固定的输入泵的能量。我们得出了最佳耦合和泵脉冲持续时间的近似分析表达式，这是环中散射损失的函数。这些结果将使研究人员能够轻松地确定微孔谐振系统的最佳设计，以生成正交呈正流状态的状态。
The intensity buildup of light inside a lossy microring resonator can be used to enhance the generation of squeezed states via spontaneous parametric downconversion (SPDC). In this work, we model the generation of squeezed light in a microring resonator that is pumped with a Gaussian pulse via a side-coupled channel waveguide. We theoretically determine the optimum pump pulse duration and ring-to-channel coupling constant to minimize the quadrature noise (maximize the squeezing) in the ring for a fixed input pump energy. We derive approximate analytic expressions for the optimal coupling and pump pulse duration as a function of scattering loss in the ring. These results will enable researchers to easily determine the optimal design of microring resonator systems for the generation of quadrature-squeezed states.
