Abstract: A compressible photonic crystal comprising a polymer with an ordered array of voids, the photonic crystal having a reflectance in a first wavelength range for light incident to its incident surface and its opposing incident surface, wherein compression against at least a portion of at least one of the surfaces shifts the reflectance to a second wavelength range in at least that portion of that surface. The crystal may be used in authentication devices of various types.

Abstract: A photonic crystal device including a photonic crystal material and an activation surface. The photonic crystal material exhibits a first reflectance spectrum in an unactivated state, and, in response to mechanical stimulation, exhibits a second reflectance spectrum in an activated state. Application of a force at an activation portion of the activation surface offset from a material-supporting portion of the activation surface causes a deformation of the photonic crystal material sufficient to bring the photonic crystal material to the activated state.

Abstract: Methods and systems for thermal printing of thermally printable photonic crystal materials and assemblies. The photonic crystal materials and assemblies are responsive to thermal stimuli, wherein temperatures above a thermal threshold results in an optically detectable change in the appearance of the materials and assemblies. Heat is selectively applied to one or more portions of the materials and assemblies, in order to thermally print a graphic onto the materials and assemblies.

Abstract: Abstract A method for thermal printing of a thermally printable photonic crystal material or assembly, the method comprising: providing the photonic crystal material or assembly, wherein the photonic crystal material or assembly contains voids, and the photonic crystal material or assembly has a void volume, the photonic crystal material or assembly having an optically detectable change in its reflection peak and a decrease in its void volume when exposed to a temperature equal to or greater than a thermal threshold of the photonic crystal material or assembly; and exposing the photonic crystal material or assembly to a heat source, the heat source being controllable to selectively apply heat to one or more portions of the photonic crystal material or assembly and not to the remainder of the photonic crystal material or assembly; wherein the heat being applied is equal to or greater than the thermal threshold of the photonic crystal material or assembly, in order to cause an optically detectable change in the one or more heated portions of the photonic crystal material or assembly. 7180661 1 (GHMatters) P95512.AU.1 27/11/2015 ~ T: ~.-. ;*TiT2 T3

Abstract: A photonic crystal device including a photonic crystal material and an infiltrating component. The photonic crystal material has an initial reflectance spectrum. An external stimulus causes the infiltrating component to migrate into or out of at least a portion of the photonic crystal material. The migration of the infiltrating component causes a change of at least the portion of the photonic crystal material to shift to a second reflectance spectrum.

Abstract: A photonic crystal device comprising: a photonic crystal material having an initial ordered structure and a viewing surface, the initial ordered structure giving rise to a first optical effect detectable from the viewing surface; and a removal layer removably attached with the viewing surface or an opposing surface of the photonic crystal material opposite to the viewing surface; wherein mechanical removal of at least a portion of the removal layer results in a structural change in at least a portion of the initial ordered structure of at least a portion of the photonic crystal material respective to the portion of the removed removal layer, thereby resulting in a changed portion different from the initial ordered structure, the changed portion giving rise to a second optical effect detectable from the viewing surface and detectably different from the first optical effect.
