Abstract: A tunable photonic crystal device comprising: alternating layers of a first material and a second material, the alternating layers comprising a responsive material, the responsive material being responsive to an external stimulus, the alternating layers having a periodic difference in refractive indices giving rise to a first reflected wavelength; wherein, in response to the external stimulus, a change in the responsive material results in a reflected wavelength of the device shifting from the first reflected wavelength to a second reflected wavelength.

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.
