Silicon wafers transformed into flat UV focusing mirrors using air cavities

By PulseAugur Editorial · [1 sources] ·

Researchers at the University of Stuttgart have developed a novel method to create flat ultraviolet focusing mirrors using silicon wafers. Instead of traditional curved optics or solid metasurfaces, this new approach utilizes nanoscale air cavities etched into silicon. These 'Mie voids' confine light primarily within the air, minimizing absorption by the silicon, which is a significant challenge for UV light. The resulting metasurfaces can focus UV light at 325 nm, demonstrating a new pathway for compact and efficient optical systems in applications like high-resolution imaging and sensing. AI
