This paper presents a new 2D surface relief grating (SRG) designed for precise color rendering in head-mounted displays (HMD) using red, green, and blue (RGB) light systems. The SRG features slanted glass pillars arranged periodically on a glass waveguide surface. Optimization of lattice constants is achieved for each RGB wavelength using finite element method simulations.
