Multicolor pattern generation in photonic bandgap composites
The generation of complex, permanent, multicolor patterns in photonic bandgap films is demonstrated. The procedure allows for the overall spatial control of the reflected color on the surface of a photonic crystal, as well as the ability to define the visible or near-IR response of a patterned region through control of the stop-band wavelength. For example, the attached image presents a 10 mm wide, orange, "tiger paw" insignia templated on a green background. See also inside front cover.
