摘要

正交极化相位的独立控制是偏振调制超表面的基础。在这里，我们提出了一种定向微扰驱动策略，可以独立控制超表面中的正交极化相位。通过在各向异性波导的短轴上引入定向扰动，可以独立调节短轴极化的相移，同时保持正交极化的相移。这种扰动也增强了电场局域化，从而导致优越的光学效率。作为概念的证明，我们展示了全庞加莱球波片和反常折射四分之一波片。我们的工作促进了实用、高效偏振光学器件的发展。

Directional Perturbation-Driven Independent Control of Orthogonally Polarized Phases in Metasurfaces.

Independent control of the orthogonally polarized phase is fundamental to polarization-modulated metasurfaces. Here, we present a directional perturbation-driven strategy enabling independent control of orthogonally polarized phases in metasurfaces. By introducing a directional perturbation along the short axis of an anisotropic waveguide, the phase shift of the short-axis polarization can be independently regulated, while the phase shift of the orthogonal polarization is maintained. This perturbation also enhances electric field localizations, leading to superior optical efficiency. As a proof of concept, we demonstrate full Poincaré sphere waveplates and an anomalous refractive quarter waveplate. Our work advances the development of practical, high-efficiency polarization optics.
