Design of 4.7 μm High-Efficiency Hybrid Dielectric Reflection Gratings
Micromachines, 2022 Traditional reflective diffraction gratings working at 4.7 μm are fabricated by metal coatings. Due to the absorption of the metal itself, the diffraction efficiency (DE) could not reach over 95%.

Polarization-Independent Two-Layer Grating With Five-Port Splitting Output Under Normal Incidence
IEEE Photonics Journal, 2020 In this paper, we report a two-layer five-port diffraction grating by a polarization-independent design under normal incidence. To be different from conventional five-port gratings, initially, we design a novel two-layer grating with operation in ...

Optimal Control of Passive Cascaded Liquid Crystal Polarization Gratings
Applied Sciences, 2023 The incidence angle of a beam entering a liquid crystal variable retarder (LCVR) and the liquid crystal polarization grating (LCPG) is greater when the LCPG is utilized in the quadrature cascade, which reduces the diffraction efficiency.
