Symposium EL12-Perspective on Applications of Metasurfaces—Advances in Metasurface Design, Fabrication, Integration and Material

Metasurfaces are artificially engineered composite surfaces with deep subwavelength units, and they exhibit optical characteristics that cannot be obtained in nature. This symposium aims at providing a forum for cross-disciplinary discussions on the applications perspective of metaphotonics. Particularly, we will focus on the rising cycle from synergy between innovations in materials science and metaphotonics. Leveraging the pioneering demonstrations of the on-demand amplitude/phase/polarization control, researchers have made continuous and significant advances in the field of metasurfaces, including space-time-modulated metasurfaces, nonlocal metasurfaces, large-scale optimizations, novel design methods beyond parameter sweeping to generate look-up tables, and high-volume fabrications. These advances have facilitated practical applications such as polarization-independent broadband metalenses with large sizes and multifunctional metasurfaces with substantially suppressed cross-talks, which could be used for computational photonics, super-resolution imaging, and biochemical sensing. To highlight the status and perspective of applications of metasurfaces, we will arrange talks on recent advances in mass production technology for metaphotonics with presenters from various fields of industry. In addition, the systematic studies in combination of novel material platform and strong light-matter interaction have empowered time-varying modulation of metasurfaces. Highly-tunable materials include low-loss phase-change materials, 2D materials, and MXene, which could be integrated with nano-resonators, paving a way toward novel applications such as LiDAR and free-space optical communications.

This symposium also covers new possibilities coming from Rendezvous between the metaphotonics and artificial intelligence (AI), focusing on both AI for photonics and photonics for AI. Various models and concepts developed in the field of AI have been implemented, yet there are still missing components such as efficient activation units. We seek to bring together researchers with diverse backgrounds from materials science, physics, electrical/chemical engineering, and computer science/vision to share recent groundbreaking advances in AI-empowered metaphotonics.
