Metadevices for DUV Molecular Sensing and Light Manipulation

Deep ultraviolet (DUV) light, spanning wavelengths from 200 to 300 nm, enables diverse applications in imaging, sensing, and medical treatments. Developing efficient and robust metasurfaces is essential for advancing DUV technologies. In this work, we explore several material platforms for DUV metasurfaces. For biosensing, we employ several durable materials to achieve strong field enhancement and stability, enabling detailed spectroscopic observations. Additionally, we present metasurfaces for DUV focusing and imaging, demonstrating functionalities unattainable with conventional optics. These results contribute to the advancement of photonics in the critical DUV wavelength range.
