Abstract: The present disclosure, in some embodiments, relates to a method of forming an integrated chip structure. The method may be performed by forming a plurality of interconnect layers within a first interconnect structure disposed over an upper surface of a first semiconductor substrate. An edge trimming process is performed to remove parts of the first interconnect structure and the first semiconductor substrate along a perimeter of the first semiconductor substrate. The edge trimming process results in the first semiconductor substrate having a recessed surface coupled to the upper surface by way of an interior sidewall disposed directly over the first semiconductor substrate. A dielectric capping structure is formed onto a sidewall of the first interconnect structure after performing the edge trimming process.

Abstract: An optical device for generating narrow-band circularly and elliptically polarized radiation, either by conversion from externally incident light or through thermal emission of heated objects. The optical device includes a metasurface comprised of unit cells, where each unit cell contains structural elements or features that break two mirror inversion symmetries of the unit cell and couple bright and dark resonances. In this manner, the optical device emits circularly polarized radiation that does not exhibit a preference for right-hand circularly polarized light or left-hand circularly polarized light incident upon it. As a result, multiple of such optical devices with different unit cell sizes, geometries and dimensions of the intra-cell elements may be implemented as a tag that thermally emits different states of circularly polarized radiation confined to multiple spectrally-narrow bands.
