Coating composition and planarization of high refractive index overcoat on gratings |
| abstract |
An optical device includes an overcoat layer on a surface-relief grating. The overcoat layer is formed by a process including: depositing a layer of a first resin material that is curable by heat or electromagnetic radiation on a surface-relief grating that includes a plurality of grating ridges and a plurality of grating grooves to at least partially fill the plurality of grating grooves, curing the layer of the first resin material, depositing a layer of a second resin material that is curable by heat or electromagnetic radiation and has a higher flowability than the first resin material on the layer of the first resin material, annealing the layer of the second resin material to allow the second resin material to flow and form a planar top surface, and curing the layer of the second resin material. |
