Enhanced infrared vision by nonlinear up-conversion in nonlocal metasurfaces
Abstract
The ability to detect and image short-wave infrared light has important applications in surveillance, autonomous navigation, and biological imaging. However, the current infrared imaging technologies often pose challenges due to their large footprints, large thermal noise, and the inability to augment infrared and visible imaging. Here, we demonstrate infrared imaging by nonlinear up conversion to the visible on an ultra-compact, high-quality lithium niobate resonant metasurface. Images with high conversion efficiency and resolution quality are obtained despite the strong nonlocality of the metasurface. We further show the possibility of edge-detection image processing augmented with direct-up conversion imaging for advanced night vision applications.
