We demonstrate a crystalline silicon oil immersion metalens with an ultra-high NA of 1.48 and a focus effectively of 48%, operating at visible wavelength. This can open a new way to use metalens efficiently in visible light regime for confocal microscopy and achromatic lenses.Juntao Li...

By arranging regular dielectric nanoposts on a sub-wavelength scale, dielectric metasurfaces could accomplish manipulation of polarization and/or phase of the transmitted light. A large number of metasurface-based devices in both near-infrared and visible regimes have been presented, such as lenses [...
The holes are clearly visible on the surface. (d) Quarter-section of 20 μm diameter metalens showing the varying hole depth. Scale bar is 2 μm. (e) Phase shift and transmission of nanoholes as the function of depth at 450 nm wavelength. (f, g) Phase derivative and the phase shift...
minimal and fabrication technologies can meet the feature size demands. For example, silicon is generally considered for near-infrared (IR) applications like lidar sensors, whereas titanium dioxide, gallium nitride, and silicon nitride are considered for camera applications in the visible wavelength ...
As a result, no metalens has demonstrated full-colour imaging in the visible wavelength. Here, we show a design and fabrication that consists of GaN-based integrated-resonant unit elements to achieve an achromatic metalens operating in the entire visible region in transmission mode. The focal ...
We use silicon-based metalenses with a numerical aperture of 0.32 and a mean measured focusing efficiency in transmission mode of 28% at a wavelength of 1550 nm. Our system is extremely compact and allows for real-time beam diagnostics by inspecting the foci amplitudes. By further analyzing ...
