Metasurfaces have emerged as a breakthrough platform for manipulating light at the nanoscale and enabling on‐demand optical functionalities for next‐generation biosensing, imaging, and light‐generating photonic devices. However, translating this technology to practical applications requires low‐cost and high‐throughput fabrication methods. Due to the limited choice of materials with suitable optical...
Metasufaces
In article number 2102232, Hatice Altug and co‐workers demonstrate a wafer‐scale nanofabrication method for manufacturing highly efficient meta‐optical elements and metasurface‐based optofluidic biosensors. The demonstrated method enables low‐cost infrared optical components and disposable sensor chips for medical diagnostics, and has the potential to accelerate the early adoption of metasurface...
