Abstract
An array of optical resonators is disclosed. The array comprises at least a first type of optical resonators each having a resonant response to an optical field at a first wavelength, and a second type of optical resonators each having a resonant response to an optical field at a second wavelength, being different from the first wavelength. The resonant responses can be selected to reduce chromatic aberrations, or to shape a profile of a light beam, or to selectively switch a near field beam.

An optical system, comprising a refractive optical element, and an array of optical resonators, said refractive optical element and said array being positioned on the same optical axis,
- wherein said array of optical resonators comprises at least a first type of optical resonators each having a resonant response to an optical field at a first wavelength, and a second type of optical resonators each having a resonant response to an optical field at a second wavelength, being different from said first wavelength, said resonant responses being selected to reduce chromatic aberrations associated with said refractive optical element.
An optical system, comprising an array of optical resonators, wherein said array of optical resonators comprises at least a first type of optical resonators each having a resonant response to an optical field at a first wavelength, and a second type of optical resonators each having a resonant response to an optical field at a second wavelength, being different from said first wavelength, wherein at least one optical resonator of said first type is laterally displaced from any optical resonator of said second type, and at least one optical resonator of said first type partially overlaps with at least one optical resonator of said second type.
An optical system, comprising an array of elongated nanoresonators, wherein said array of elongated nanoresonators is spatially ordered to polarize or effect light polarization over a cross section of a light beam, or an image, for at least one wavelength.
