Abstract
Embodiments of the invention are directed compositions and devices that include a spatially-variant lattice (SVL), such as spatially variant photonic crystals (SVPC), as well as methods for making and using the same. In particular, the compositions and devices include SVPCs that are configured for manipulating the path and/or properties of electromagnetic radiation flowing through the SVPC in a variety of ways.
Claims22
A spatially-variant lattice having one or more attributes of the periodic structure spatially vary comprising a lattice constructed from a plurality of unit cells, wherein the unit cells vary, as a function of position within the lattice, in a structural or material property comprising one or more of unit-cell periodicity, orientation in space, symmetry, material composition, fill factor, or pattern within the unit cell;
- and unintentional deformations are minimized to preserve properties of the lattice.
An anti-reflective spatially variant photonic crystal (SVPC) comprising a lattice forming a plurality of unit cells, the lattice having three dimensions and forming at least one face, with at least one face comprising an array of protrusions that suppress scattering of a light beam entering or leaving the lattice.
-23. (canceled)
A multiplexed spatially variant photonic crystal (SVPC) for manipulating electromagnetic radiation comprising a lattice comprising a plurality of unit cells wherein the unit cells vary as a function of position within the lattice in two or more structural or material properties for manipulation of two or more attributes of electromagnetic radiation passing through the SVPC.
