3D phase-matching conditions for the generation of entangled triplets by chi(2) interlinked interactions
摘要：
本文对满足相位匹配条件的两个相互关联的二阶非线性过程的相互作用几何进行了解析计算。该方法是为I型单轴晶体开发的，并给出了在屏幕上的相互作用所产生的纠缠三重态的晶体以外的位置。分析结果进行了比较，实现在宏观制度的实验。初步测试，以确定三胞胎也进行了强度相关性的基础上。
英文摘要：
An analytical calculation of the interaction geometry of two interlinked second-order nonlinear processes fulfilling phase-matching conditions is presented. The method is developed for type-I uniaxial crystals and gives the positions on a screen beyond the crystal of the entangled triplets generated by the interactions. The analytical results are compared to experiments realized in the macroscopic regime. Preliminary tests to identify the triplets are also performed based on intensity correlations.
