Abstract

Chiral photons have the potential to advance information technologies due to their robustness in carrying binary data against noisy backgrounds as well as their capacity for constructing single-photon isolators and circulators through nonreciprocal photon propagation. In this Perspective, we highlight recent efforts to generate chiral single photons using circularly polarized light sources. We delve into possible future technologies that integrate these light sources with other active optical elements as a versatile platform for information processing.

摘要

手性光子有潜力推动信息技术发展，这是因为它们在携带二进制数据对抗噪声背景时具有稳健性，以及具备通过非互易光子传播构建单光子隔离器和环行器的能力。在这篇视角文章中，我们重点介绍了利用圆偏振光源产生手性单光子的近期研究成果。我们深入探讨了未来可能的技术，这些技术将这些光源与其他有源光学元件集成，作为一个通用的信息处理平台。
