Abstract

original image

Rejection-wavelength tuning is achieved by combining the mechanochromic response of photonic bandgap composites with the intrinsic electroactive properties of dielectric thin films. By straining the composite electrode, the photonic crystal interparticle lattice constant is varied in situ (see Figure). These simple-to-make films may find use in photonic devices that require a compact light-propagation controlling component.
