Electric-field-induced rejection wavelength tuning of photonic bandgap composites

Rejection-wavelength tuning is achieved by combining the mechano-chromic response of photonic bandgap Composites with the intrinsic electro-active properties of dielectric thin films. 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.
