optical projection, augmented/virtual reality, and miniaturized medical imaging tools. Typically, aberration-free imaging with a wide FOV is achieved by stacking multiple refractive lenses (as in a “fisheye” lens), adding to the size and weight of the optical system....
We show that for metalenses with a relatively large numerical aperture (NA), there is a tradeoff between the maximum achievable bandwidth and the FOV; interestingly, however, the bandwidth reduction saturates beyond a certain FOV that depends on the NA of the metalens. These findings may provide...
Recently, the emergency of meta- optics provides an alternative to constructing compact and lightweight large-FOV metalens through elaborated phase modulation within a flat surface, showing great potential in surveillance, unmanned vehicles, onboard planes or satel- lites, medical science, and other ...
This points to thescientif i cally and technologically important questions: isthere a fundamental trade-of f between the FOV and thethickness of a metalens system, or lenses in general? If so,what is the minimal thickness allowed by physical laws?Light propagating through disordered media exhibits...
High-Speed Duplex Free Space Optical Communication System Assisted by a Wide-Field-of-View Metalens Free space optical communication (FSO) has gained significant attention due to the growing demand for a high information capacity. For FSO between multiple... Nan He,Tingbiao Guo,Jiahan Tian,......
In conclusion, we have demonstrated a versatile approach to create highly efficient, wide-FOV plasmonic metasurface-based waveplates that control the polarization response of light over more than an octave bandwidth from the visible to the near-IR. The ultrathin reflective waveplates are realized by...
We present a BA&WFOV metalens-doublet with an f-number of 3.9, a full field of view (FOV) of 68 degrees, and a wavelength range from 640 nm to 820 nm . This metalens-doublet exhibits diffraction -limited focusing with an average absolute focusing efficiency of 16% and an average ...
