Abstract

A metasurface lens assembly to perform chromatic separation includes a first layer with a plurality of nanofins extending transversely there from and each being optically anisotropic and transmissive to light in the visible spectrum and having an optical characteristic that is set according to a phase profile. A second layer is spaced apart from the first layer and includes a plurality of photosensitive subpixels each associated with a different color. In operation, many beams of light may be directed onto the metasurface lens from a source with each beam of light having a plurality of component colors. The nanofins may function in combination with one another according to the phase profile to bend and focus the beams of light onto the second layer with each of the component colors being bent and focused differently to direct the component colors onto corresponding ones of the photosensitive subpixels.
