Design and Fabrication of Large-Scale Meta-Optic Devices

Metasurfaces, artificially engineered ultrathin subwavelength nanostructures with exceptional light control capabilities, have the potential to revolutionize conventional optics. However, the traditional methods for creating these metasurfaces are slow, expensive, and lack scalability. To address this, we have developed a cost-effective and scalable design and fabrication method for large-scale meta-optic devices that work in both the visible and infrared regimes. We showcase several examples, including a single-lens telescope using a wafer-scale metalens, inch-scale meta-optic correctors, and a metasurface-enabled real-time hyperspectro-polarizmetry camera. Our technology facilitates versatile light control in scalable, compact, multifunctional flat optics devices with significant potential for real-world applications.
