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%.

A 1 × 2 Two-Dimensional Slanted Grating Based on Double-Layer Cylindrical Structure
Applied Sciences, 2023 Diffraction gratings play an increasingly important role in various planar optical systems, such as near-eye display systems for virtual reality (VR) and augmented reality (AR). The slanted gratings have more advantages than other elements.
