Abstract
AbstractThe 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 large footprint, large thermal noise and inability to augment infrared and visible imaging. Here, infrared imaging is demonstrated by nonlinear up‐conversion to the visible in an ultra‐compact, high‐quality‐factor lithium niobate resonant metasurface. Images with high conversion efficiency and resolution quality are obtained despite the strong nonlocality of the metasurface. The possibility of edge‐detection image processing augmented with direct up‐conversion imaging for advanced night vision applications is further shown.
