Abstract
Systems and methods for embedding optical elements in an optical device are described. A method includes: providing a resin layer with a replica surface topography; cutting the resin layer to form an optical element layer that includes the replica surface topography; coating the replica surface topography with a layer; providing a substrate having a substrate refractive index; and connecting the layer to the substrate with an index matching material having a matching refractive index that is substantially equal to the substrate refractive index. The systems and methods provide advantages in that surface topography is replicated with enhanced overall cost effectiveness.
