摘要

偏振光子本质上是中性粒子,因此不能直接与外场耦合,从而阻碍了光子与外场的有效相互作用。在这里,我们从理论上确定了极化光子的等效自旋-1/2 模型,并合成了一个磁化矢量,用于在工程各向异性介质中耦合不同的极化光子。合成磁场可以通过电子工程来操纵伪自旋-1/2 光子的磁矩,从而观察到洛伦兹力和类似的斯特恩-格拉赫效应。我们通过使用不同的自旋(包括纯单极化自旋和相互双极化混合自旋)来实验证明这些基本效应。我们还通过使用具有非难拓扑结构的自旋来证明高阶斯特恩-格拉赫效应。我们的发现可以使基于极化的元素在极化选择和转换方面得到潜在应用,从而有利于经典和量子信息处理。

Electrically engineering synthetic magnetic fields for polarized photons
Polarized photons are, in essence, neutral particles and therefore do not couple directly to external fields, thus hampering the effective interaction of photons with external fields. Here, we theoretically identify an equivalent spin-1/2 model for polarized photons and synthesize a magnetization vector for coupling differently polarized photons in an engineered anisotropic medium. The synthetic magnetic field can be electrically engineered to manipulate the magnetic moments of the pseudo-spin-1/2 photons, leading to observation of the Lorentz force and analogous Stern–Gerlach effect. We experimentally demonstrate these fundamental effects by using different spins, including purely single-polarization spins and mutually two-polarization mixing spins. We also demonstrate the higher-order Stern–Gerlach effect by using spins having nontrivial topological structures. Our findings could enable polarization-based elements with potential applications in polarization selection and conversion, benefiting classical and quantum information processing.
