Multiwavelength polarization-insensitive lenses based on dielectric metasurfaces with meta-molecules
Metasurfaces are nanostructured devices composed of arrays of subwavelength scatterers (or meta-atoms) that manipulate the wavefront, polarization, or intensity of light. Like most other diffractive optical devices, metasurfaces are designed to operate optimally at one wavelength. Here, we present a method for designing multiwavelength metasurfaces using unit cells with multiple meta-atoms, or ...
متن کاملMultiwavelength metasurfaces through spatial multiplexing
Metasurfaces are two-dimensional arrangements of optical scatterers rationally arranged to control optical wavefronts. Despite the significant advances made in wavefront engineering through metasurfaces, most of these devices are designed for and operate at a single wavelength. Here we show that spatial multiplexing schemes can be applied to increase the number of operation wavelengths. We use ...
متن کاملDielectric metasurfaces for complete control of phase and polarization with subwavelength spatial resolution and high transmission.
Metasurfaces are planar structures that locally modify the polarization, phase and amplitude of light in reflection or transmission, thus enabling lithographically patterned flat optical components with functionalities controlled by design. Transmissive metasurfaces are especially important, as most optical systems used in practice operate in transmission. Several types of transmissive metasurf...
متن کاملMie-resonant dielectric nanostructures as a platform for functional nanophotonics
This scheme gives the possibility of matching the coherence time of the broadband squeezed light to the response time of the photodetector. We finally discuss a temporal imaging scheme which allows to partially compensating the frequency dispersion of the OPA. All-dielectric nanoparticles with a high refractive index support strong localized electric and magnetic multipolar Mie-type resonances....
متن کاملMetasurfaces based dual wavelength diffractive lenses.
We demonstrate experimentally and by simulations a method for using thin nanostructured plasmonic metasurfaces to design diffractive Fresnel zone plate lenses that focus pairs of wavelengths to a single focal point. The metasurfaces are made of tightly packed cross and rod shaped optical nanoantennas with strong polarization and wavelength selectivity. This selectivity allows multiplexing two d...
