Abstract

Triangular cross-section color center photonics in silicon carbide is a leading candidate for scalable implementation of quantum hardware. Within this geometry, we model low-loss beam splitters for applications in key quantum optical operations such as entanglement and single-photon interferometry. We consider triangular cross-section single-mode waveguides for the design of a directional coupler. We optimize parameters for a 50:50 beam splitter. Finally, we test the experimental feasibility of the designs by fabricating triangular waveguides in an ion beam etching process and identify suitable designs for short-term implementation.

用于量子信息处理的碳化硅三角截面分束器
碳化硅中的三角形截面色心光子学是可扩展量子硬件的主要候选方案。在这种几何结构中,我们为纠缠和单光子干涉测量等关键量子光学操作中应用的低损耗分束器建模。我们考虑用三角形截面单模波导来设计定向耦合器。我们优化了 50:50 分光器的参数。最后,我们通过离子束蚀刻工艺制作三角形波导,测试了设计的实验可行性,并确定了适合短期实施的设计。
