标题： Chip-Scale Atomic Birefringent Diffractive-Optical-Elements

摘要： 在磁场存在的情况下光与蒸气的相互作用对于许多量子技术和应用来说是基础性的。最近，能够几何地将原子限制到周期性结构的能力使得芯片规模的、微加工的混合原子衍射光学元件得以创建。然而，将磁场应用于这些结构仍然没有被充分探索，这为基本和应用洞察提供了潜力。在这里，我们展示了受磁场影响的原子衍射光学元件的测量结果。与法拉第介质中众所周知的偏振旋转相反，这些衍射原子元件表现出额外的快速振荡旋转项，我们通过理论和实验验证了这一点。此外，我们发现引入空间变化的磁场会导致条纹可见度的降低，这可以用于梯度计应用。这些效应一起建立了一个芯片规模的平台，在该平台上衍射和量子传感是不可分割地共同设计的，揭示了以前无法进入的原子-光子-磁相互作用区域。通过探测周期性限制蒸气的磁光响应，我们的结果为集成智能单元磁力计奠定了基础，并为平面光学启用的量子光子器件开辟了新的途径。 显示英文摘要

摘要： The interaction between light and vapors in the presence of magnetic fields is fundamental to many quantum technologies and applications. Recently, the ability to geometrically confine atoms into periodic structures has enabled the creation of chip-scale, micromachined hybrid atomic-diffractive optical elements. However, applying magnetic fields to such structures remains largely unexplored, offering potential for both fundamental and applied insights. Here, we present measurements of an atomic-diffractive optical element subject to magnetic fields. In contrast to the well-known polarization rotation in a Faraday medium, these diffractive atomic elements exhibit additional, rapidly oscillating rotation terms, which we validate both theoretically and experimentally. Moreover, we find that the introduction of spatially varying magnetic fields leads to a reduction in fringe visibility, which can be leveraged for gradiometric applications. Together, these effects establish a chip-scale platform where diffraction and quantum sensing are inseparably co-engineered, unveiling previously inaccessible regimes of atom-photon-magnetic interaction. By probing the magneto-optic response of periodically confined vapors, our results lay the groundwork for integrated smart-cell magnetometers and open new avenues for flat-optics-enabled quantum photonic devices.
