Abstract
We investigate the use of period-doubling perturbations for switching on / off absorptive and emissive processes in microstructured materials. We first design periodic gratings to support guided resonance modes that enhance absorption in the vicinity of the resonance wavelength. We then introduce a refractive index perturbation that effectively doubles the period of the original grating. Given proper design, we can introduce a photonic band gap at the edge of the new Brillouin zone, "erasing" the original resonance mode at the operating wavelength. We discuss applications to electrically-modulated emissive control in both visible-wavelength, photoemissive and infrared-wavelength, thermally emissive structures.
