Claim 16:
17. A product comprising:
a. a support structure,
b. a first plurality of high-index dielectric structures, said first plurality of high-index dielectric structures being supported by the support structure,
c. a second plurality of high-index dielectric structures, wherein the second plurality of high-index dielectric structures is a sub-set of the first plurality of high-index dielectric structures,
wherein a geometry specifically of the second plurality of high-index dielectric structures may be changed, wherein said changing the geometry may carried out by photothermally melting at least a portion of each of the high-index dielectric structures within the second plurality of high-index dielectric structures by irradiating the second plurality of high-index dielectric structures with incident electromagnetic radiation having an incident intensity in a plane of the second plurality of high-index dielectric structures and thereby exciting resonances associated with each of the high-index dielectric structures within the second plurality of high-index dielectric structures,
wherein said support structure comprises a first plurality of topographical features comprising topographical pillars or topographical holes formed on a surface of the support structure,
and wherein the first plurality of high-index dielectric structures are given by:
a plurality of high-index dielectric structures on said topographical pillars or in said topographical holes,

and
a plurality of holes in a high-index dielectric film, wherein said holes correspond to said topographical features,

and wherein the relative permittivity at 532 nm of the first plurality of high-index dielectric structures is equal to or larger than 5.
