Abstract
Official abstract text for this publication.
A multi-layer photonic structure may include alternating layers of high index material and low index material having a form [H(LH) N ] where, H is a layer of high index material, L is a layer of low index material and N is a number of pairs of layers of high index material and layers of low index material. N may be an integer≧1. The low index dielectric material may have an index of refraction n L from about 1.3 to about 2.5. The high index dielectric material may have an index of refraction n H from about 1.8 to about 3.5, wherein n H >n L and the multi-layer photonic structure comprises a reflectivity band of greater than about 200 nm for light having angles of incidence from about 0 degrees to about 80 degrees relative to the multi-layer photonic structure. The multi-layer photonic structure may be incorporated into a paint or coating system thereby forming an omni-directional reflective paint or coating.
First claim
Opening claim text (preview).
What is claimed is: 1. A multi-layer photonic structure comprising alternating layers of high index material and low index material having a form [0.5 L H (LH) N 0.5 L] where H is a layer of high index material, L is a layer of low index material, 0.5 L are half layers of low index material positioned on a top and a bottom of the multilayer photonic structure, and N is a number of pairs of layers of high index material and layers of low index material, wherein: N is an integer≧1; the low index material has an index of refraction n L from about 1.3 to about 2.5; the high index material has an index of refraction n H of greater than or equal to about 3.0; the multilayer photonic structure is substantially transparent to visible wavelengths of light and has an IR reflectivity band and a UV reflectivity band; and the multi-layer photonic structure has a range to mid-range ratio greater than about 20% in a transverse electric mode and a transverse magnetic mode, and wherein the range to mid-range ratio for the transverse electric mode is determined by η TE = 2 λ long TE ( θ 0 = 90 ° ) - λ Short TE ( θ 0 = 0 ° ) λ long TE ( θ 0 = 90 ° ) + λ Short TE ( θ 0 = 0 ° ) , where λ long TE a first band edge for a first long wavelength in the transverse electric mode and λ short TE is a second band edge for a first short wavelength in the transverse electric mode, and the range to mid-range ratio for the transverse magnetic mode is determined by η TM = 2 λ long TM ( θ 0 = 90 ° ) - λ Short TM ( θ 0 = 0 ° ) λ long TM ( θ 0 = 90 ° ) + λ Short TM ( θ 0 = 0 ° )
