Title:
METASURFACES FOR REDIRECTING LIGHT AND FABRICATING METHODS
Document Type and Number:
Japanese Patent JP2023071781
Kind Code:
A
Abstract:
To provide favorable metasurfaces for redirecting light and fabricating methods.SOLUTION: A display system comprises a waveguide having light incoupling or light outcoupling optical elements formed of a metasurface. The metasurface is of a multilevel (e.g., bi-level) structure having a first level defined by spaced protrusions formed of a first optically transmissive material and a second optically transmissive material between the protrusions. The metasurface also includes a second level formed by the second optically transmissive material. The protrusions on the first level may be patterned by nanoimprinting the first optically transmissive material, and the second optically transmissive material may be deposited over and between the patterned protrusions. The widths of the protrusions and the spacing between the protrusions may be selected to diffract light, and a pitch of the protrusions may be 10-600 nm.SELECTED DRAWING: Figure 11
