Light intensity modulation is crucial to the development of optical imaging, optical sensing, and optical switch. The light intensity modulation methods, such as changing structural parameters, external temperature, or external voltage make the control process time consuming and complex. The plasmonic polarization modulation is an effective way to modulate light intensity, but this method is limited by the excitation of surface plasmons with transverse magnetic (TM) polarized light. Herein, we report another polarization modulation method of light intensity based on guided mode resonance in the dielectric grating excited by transverse electric (TE) polarized light. The nanosystem is composed of Si grating and TiN substrate. By adjusting the polarization states of the incident light from TE to TM, the proposed nanosystem exhibits an outstanding light intensity modulation performance with a relative modulation depth of 25833%. The proposed method provides another way for modulating light intensity, which has potential applications of optical switch, optical imaging, and optical anti-counterfeiting.

“…As period and depth of the optical structure of the photonic crystal are fixed, the structural color depends on the observation angle [3–4]. Studies show that photonic crystals with grating pattern are the favorable candidates for a variety of applications, not only due to their compact structures, simple fabrication process and excellent spectral characteristics, but also because reflection wavelength and observation angle are closely connected [5–7]. At present, nanoimprint lithography (NIL) and self-assembly are the two main methods to prepare photonic crystals with grating pattern [8–11].…”

The structural color of angle-sensitive photonic crystals has attracted great interest because of a possible application in visual sensors. The appearance of a photonic crystal is mainly influenced by the optical properties, structural parameters and the observation angle. In this work, an angle-sensitive photonic crystal with nanoscale gratings was fabricated through reverse nanoimprint lithography. The periodicity and the structural color were investigated through measuring reflection spectra. The structural color of the photonic crystal has a period of 90°. Distinctive colors spanning the entire visible spectrum can be seen when the crystal is rotated. In addition, there is a blue-shift of the peak wavelength when the observation angle is increased. An equation for the observed wavelength as a function of the observation angle is proposed.

“…The metamaterial perfect absorbers (MMPA) [25]- [30] are one kind of plasmonic metamaterials with nearly 100% absorption at the certain wavelength based on the excitation surface plasmon resonances (SPR) and localized surface plasmon resonances (LSPR). It's found that the selective absorption of MMPA can manipulate the reflection spectrum to generate different colors by changing the nanostructure [31]- [33]. Due to the single-band characteristic of most MMPA, the reflective artificial structure colors are usually not the red, green and blue (RGB) but their complementary colors: cyan, magenta, and yellow (CMR).…”

“…The 1D polarization-controllable MMPA (such as 1D grating) behaves like a 'switch' because it excites only the resonant modes for TE-polarized light [44]- [48]. Cui et al have reported the polarization-controllable structure color based on 1D grating MMPA, which demonstrates some color for TE-polarized incident white light, while white for TM-polarized incident white light [33]. In order to gradually changing the structural color from one color to another (not white), the absorption peak wavelength must be shifted with polarization.…”

The polarization-controllable structure color has been theoretically designed by utilizing metamaterial resonators with polarization-dependent multiband absorption peaks. Our designed nanostructure, consisting of the periodic circle and ellipse resonators, shows above 80% reflectivity from 502 to 553 nm (the green structure color) for TE-polarized incident white light, but above 80% reflectivity from 610 to 750 nm (the red structure color) for TMpolarized incident white light. Therefore, the structure colors gradually change from green to red when the polarization angles increasing from 0°(TE) to 90°(TM). The polarizationcontrollable structure colors come from the polarization-dependent multiband absorption peaks. When the polarization changes from TE to TM, the absorption peaks shift from 454, 624, and 714 nm to 454, 498, and 550 nm. The physical mechanism is explained by the electromagnetic fields distribution and the equivalent LC circuit model. It can keep the structure color for a wide incident angle.
