Enhancing reality: Metalens array and color filter integration for immersive AR/VR

초록

AR and VR technologies are advancing rapidly, offering immersive experiences in the digital world. Researchers are exploring new ways to improve visual quality and user immersion. One promising solution is combining Metalens Arrays and Color Filters, which can enhance AR/VR experiences by manipulating light at a tiny scale. These technologies, integrated into AR/VR glasses, promise to revolutionize various fields by improving image resolution, color accuracy, and brightness. Users can expect more lifelike virtual environments, allowing deeper exploration and engagement in simulations and applications. Overall, the integration of Metalens Arrays and Color Filters represents a significant advancement in immersive experiences, opening up new possibilities in entertainment, education, and professional fields. In our research, we create a reflective Color Filter (CF) using a metasurface for RGB color filtering intended for AR/VR displays. This CF reflects light of specific wavelengths for desired colors while absorbing the rest. We assess color purity and accuracy using linear plots in Ansys Lumerical FDTD and chromaticity diagrams. Additionally, to focus this filtered light at various spots on the same plane, we design a metalens array in Ansys Lumerical FDTD and analyze its focusing profile. © 2024 SPIE.
