摘要:

本文提出了一种在周期性极化的三波导定向耦合器中通过II型自发参量下转换过程产生高维模纠缠的方法。我们表明,通过适当的设计,有可能实现两个光子占据三个不同的空间模式的输出状态。使用这种波导结构的优点是其灵活性和设计空间可用性,以实现在下转换过程中产生的光子对的期望特性

英文摘要:

In this paper, we propose a method for the generation of higher dimensional modal entanglement through type II spontaneous parametric down conversion process using a three waveguide directional coupler in a periodically poled lithium niobate substrate. We show that by a proper design, it is possible to achieve an output state of two photons occupying three different spatial modes. The advantage of using such waveguide structure is its flexibility and the design space availability to achieve desired characteristics of the photon pairs generated in the down conversion process
