Zuo, Haijie; Choi, Duk-Yong; Gai, Xin; Ma, Pan; Xu, Lei; Neshev, Dragomir; Zhang, Baoping; Luther-Davies, Barry

Description

Metasurfaces-based flat optics, which can make use of existing foundry planar technology for high-throughput production, allows the arbitrary control of the wavefront and polarization of light within subwavelength thick structures. So far, however, flat optics for the mid-infrared (MIR) has received far less attention than devices operating at visible or near-infrared wavelengths. Here, polarization-insensitive, highly efficient, all-dielectric metalenses operating in the MIR around 4 µm are...[Show more]
