FABrication of 3D metasurfaces to enable the next generation of high efficiency optical products

该公司将开发一种工业表面“涂层”技术，该技术利用多光子光刻和工艺建模方面的突破，以适合批量生产的生产能力制造高分辨率的3D超表面。这些超表面将能够以前所未有的灵活性操控光线，并将通过取代目前用于提高光学产品效率和性能的笨重部件和/或化学涂层，为设计和制造更小、更轻和更环保的产品提供可能性。该项目将探索快速(&gt；10cm2/min)高分辨率(小于200纳米)3D结构的微制造的新方法，并开发新的生产工具，以优化超表面的设计并将其集成到功能产品中。然后，这些创新将被扩展用于商业应用，并集成到具有质量保证和控制系统的工业平台中，从而能够在一系列基板上以前所未有的生产率、分辨率、灵活性和可靠性制造3D亚表面。该技术的应用及其有助于设计和制造更可持续和更循环的欧洲商品的潜力也将在一系列使用案例中得到展示。该平台将用于在光学部件(透镜、光管和微光学阵列)上涂覆定制的准表面，并展示当这些部件集成到功能光学系统(相机、车灯和光伏电池)的设计和制造中时，可以显著提高它们的效率，同时减少它们的环境足迹。

FABulous will develop an industrial surface ‘coating’ technology that exploits breakthroughs in multiphoton lithography and process modelling to manufacture high resolution 3D metasurfaces at a throughput viable for series production. These metasurfaces will be capable of manipulating light with unprecedented flexibility and will open the possibility of designing and manufacturing smaller, lighter, and more environmentally friendly products, through the replacement of bulky components and/or the chemical coatings currently used to enhance the efficiency and performance of optical products. The project will explore novel methods for rapid (>10cm2/min) microfabrication of high-resolution (smaller than 200nm) 3D structures, and the development of new production tools to optimise the design and integration of the metasurfaces into functional products. These innovations will then be scaled for commercial applications and integrated into an industrial platform with a quality assurance and control system, enabling the fabrication of 3D metasurfaces on a range of substrates with unprecedented productivity, resolution, flexibility, and reliability. The application of the technology and its potential to contribute to the design and manufacturing of more sustainable and circular European goods will also be demonstrated in a series of uses cases. The platform will be used to coat optical components (lenses, light pipes, and micro-optics arrays) with custom metasurfaces, and demonstrate that these components, when integrated into the design and manufacturing of functional optical systems (cameras, automotive lights and PV cells), can significantly improve their efficiency whilst in parallel reducing their environmental footprint.
