论文摘要
刺激的发射断层扫描是一种强大而成功的技术,既可以改善分辨率,又可以在实验上简化确定两光构成模态性能的任务。在当前的手稿中,我们提供了对集合的理论描述,适用于非线性介质和通过成对生成光子的泵场之间的任何二次耦合方案。我们使用我们的结果不仅获得有关相关模态函数模量的信息,而且还获得了任何模式的阶段,我们讨论了时间频变量的特定情况以及测量分辨率所涉及的数量和局限性。
Stimulated emission tomography is a powerful and successful technique to both improve the resolution and experimentally simplify the task of determining the modal properties of biphotons. In the present manuscript we provide a theoretical description of SET valid for any quadratic coupling regime between a non-linear medium and pump fields generating photons by pairs. We use our results to obtain not only information about the associated modal function modulus but also its phase, for any mode, and we discuss the specific case of time-frequency variables as well as the quantities and limitations involved in the measurement resolution.
