Patent ID: 8368990

Claim:
A device comprising: a substrate; a first optical-field confining structure located on the substrate; a second optical-field confining structure located on the substrate, the second optical-field confining structure spaced apart from the first optical-field confining structure; and a composite structure located between the first and second optical-field confining structures, the composite structure comprising: an embedding structure with a surface to receive photons, and a plurality of quantum structures located in the embedding structure, wherein the first optical-field confining structure and the second optical-field confining structure are configured to achieve a desired confinement of an electrical field of the photons having a wavelength in a specific spectrum, and wherein the first and second optical field confining structures are configured to substantially confine an optical field of the photons to enable the quantum structures to selectively operate in a mott insulator mode or a superfluid mode depending on a wavelength of the received photons.
