Query: Color filter arrays based on dielectric metasurface elements   Digital imaging has been steadily improving over the past decades and we are
moving towards a wide use of multi- and hyperspectral cameras. A key component
of such imaging systems are color filter arrays, which define the spectrum of
light detected by each camera pixel. Hence, it is essential to develop a
variable, robust and scalable way for controlling the transmission of light.
Nanostructured surfaces, also known as metasurfaces, offer a promising solution
as their transmission spectra can be controlled by shaping the
wavelength-dependent scattering properties of their constituting elements. Here
we present, metasurfaces based on silicon nanodisks, which provide filter
functions with amplitudes reaching 70-90% of transmission, and well suitable
for RGB and CMY color filter arrays, the initial stage towards the further
development of hyperspectral filters. We suggest and discuss possible ways to
expand the color gamut and improve the color values of such optical filters.
