Abstract
Metasurfaces are a promising technology that can serve as a compact alternative to conventional optics while providing multiple functions depending on the properties of the incident light, such as the wavelength, polarization, and incident angle. Here, we demonstrate a hybrid visible/near-infrared dielectric metaoptic capable of reflecting 940 nm light in a specified direction while allowing transmission of visible light (450–750 nm). This dual functionality is achieved by combining an aperiodic distributed Bragg reflector with dielectric meta-atoms. Experimental demonstration is also reported, showing an anomalous reflection of near-infrared light within a 20° full field-of-view and the transmission of wavelengths from 450 nm to 750 nm.
