Seyedeh Mahsa Kamali, Ehsan Arbabi, Amir Arbabi, Andrei Faraon

摘要:

在过去的几年中,超颖表面已被用来展示光学元件和系统的能力,超过传统的衍射光学。在这里,我们回顾了这些最新的发展,重点是介电结构的整形光学波前。我们讨论了实现高效率的陡峭的相位梯度,同时偏振和相位控制,控制色散,控制角响应的机制。然后,我们回顾了在成像,共形光学,可调器件和光学系统中的应用。最后,我们展望了未来的潜力和需要克服的挑战。

英文摘要:

During the past few years, metasurfaces have been used to demonstrate optical elements and systems with capabilities that surpass those of conventional diffractive optics. Here we review some of these recent developments with a focus on dielectric structures for shaping optical wavefronts. We discuss the mechanisms for achieving steep phase gradients with high efficiency, simultaneous polarization and phase control, controlling the chromatic dispersion, and controlling the angular response. Then we review applications in imaging, conformal optics, tunable devices, and optical systems. We conclude with an outlook on future potentials and challenges that need to be overcome.
