Abstract
We demonstrate that properly designed one-dimensional guided-mode resonance filters (GMRFs) with only one grating layer can exhibit a nonpolarizing resonant filtering effect under normal incidence. A sinusoidal profile nonpolarizing GMRF is realized by photoinduced surface-relief grating formation on thin films of polymer– azobenzene complexes and subsequent atomic layer deposition, showing the feasibility of fabrication of such compact GMRFs.
