“…For such filters, a broad color-tuning characteristic is certainly desirable for their applications in three-dimensional projection display systems, ultra-fast displays, security tags, polarization detectors, and active color pixels567. Devices that rely on the guided-mode resonance (GMR) effect are especially attractive for their simple design and fabrication, proper bandwidth, sound color purity, compact size, and flexible transfer characteristics78910; however, they are mostly limited to a static case wherein the emergence of a predetermined single color is facilitated. In an attempt to obtain adaptively controlled spectral characteristics, various schemes that tapped into the adjustment of the angle of incidence or the grating period, the thermo-/electro-optic effect, and the mechanical control of the device position were previously attempted910111213; however, a high drive voltage was required in all cases, and moreover, the devices needed to be accurately aligned, thereby limiting their tuning range.…”
