Three-dimensional Dammann array
TL;DR: It is shown that this arrangement makes it possible to achieve 3D Dammann arrays with micrometer-sized focus spots and focus spacings of tens of micrometers for various practical applications, such as 3D parallel micro- and nanomachining, 3D simultaneous optical manipulation,3D optical data storage, and multifocal fluorescence microscope, etc.

Polarization-Independent Absorber Based on a Cascaded Metal–Dielectric Grating Structure
TL;DR: In this paper, a polarization independent spectrum selective absorber based on two pairs of stacked metal-dielectric grating structures is presented for the infrared frequencies, and the near-unity absorption with polarization independence is observed under normal incidence.

TE polarization selective absorber based on metal-dielectric grating structure for infrared frequencies
TL;DR: In this paper, a TE polarization spectrum selective absorber exhibiting near 100% absorption at the resonant wavelength is investigated for infrared frequencies, which is attributed to guided mode resonance in different dielectric spacer layers.

Beam splitting of a double-groove fused-silica grating under normal incidence
TL;DR: In this paper, a double-groove fused-silica gratings for 1 × 5 and 1 × 7 TE-polarization beam splitting under normal incidence was studied, and the average diffraction efficiencies of the two gratings were both more than 95% with uniformity of better than 2%.

Polarization-independent wideband mixed metal dielectric reflective gratings
TL;DR: A polarization-independent wideband mixed metal dielectric grating with high efficiency of the -1st order is analyzed and designed in Littrow mounting and geometric parameters of the reflective grating are exactly obtained.
