Abstract Nanophotonics research relies heavily on state-of-the-art and costly nano and microfabrication technologies. While such technologies are fairly mature, their implementation in large-scale manufacturing of photonic devices is not straightforward. This is a major roadblock for integrating nanophotonic functionalities, such as flat optics or high definition, ink-free color printing, into real life applications. In particular, optical metasurfaces – nanoscale textured surfaces with engineered optical properties – hold great potential for a myriad of such applications. Digital laser printing has recently been introduced as a low-cost lithography solution, which allows the fabrication of high-resolution features on optical substrates. By exploiting resonant opto-thermal modification of individual nanoscale elements, laser printing can achieve nanometer-sized resolution. In addition, the concept of digital resonant laser printing at the nanoscale supports mass-customization and may therefore convert nanophotonic science into everyday consumer products.

数字共振激光打印：连接纳米光子科学和消费产品

摘要 纳米光子学研究严重依赖于最先进且昂贵的纳米和微加工技术。虽然这些技术相当成熟，但它们在光子器件的大规模制造中的实施并不简单。这是将纳米光子功能（例如平面光学或高清无墨彩色印刷）集成到现实生活应用中的主要障碍。特别是，光学超表面——具有工程光学特性的纳米级纹理表面——在无数此类应用中具有巨大的潜力。最近引入了数字激光打印作为一种低成本的光刻解决方案，它允许在光学基板上制造高分辨率特征。通过利用单个纳米级元件的共振光热改性，激光打印可达到纳米级分辨率。此外，纳米级数字共振激光打印的概念支持大规模定制，因此可以将纳米光子科学转化为日常消费产品。
