摘要

摘要在通信系统、传感器和制造技术等应用中，元表面能以更紧凑的外形取代散装光学元件。然而，由于需要选择同时提供所需的振幅和相位调制的元原子，而这些元原子的设计和制造又要对制造误差保持稳定，因此具有很大的挑战性。在此，我们开发了两种设计启发式方法，以帮助将元原子向下选择到灵敏度信息库中，其基础是选择灵敏度最低的元原子或将元原子间的相对灵敏度最小化。我们在偏振相关相位掩模上对这两种方法进行了评估，并比较了由此产生的相位和强度误差。

Design of fabrication-tolerant meta-atoms for polarization-multiplexed metasurfaces

Abstract

Metasurfaces can replace bulk optical components in a more compact form factor in applications including communication systems, sensors, and manufacturing technology. However, their design and fabrication is challenging due to competing demands of selecting meta-atoms that simultaneously provide the required amplitude and phase modulation while being robust to fabrication errors. Here, we develop two design heuristics to assist with the down-selection of meta-atoms into sensitivity-informed libraries, based on either selecting meta-atoms with minimal sensitivity or minimizing the relative sensitivities between meta-atoms. We evaluate both methods on a polarization-dependent phase mask and compare the resulting phase and intensity errors.
