Immersed fresnel structure with curable liquid polymer

A non-transitory computer readable medium storing instructions for manufacturing an immersed Fresnel structure, the instructions when executed by a processor cause the processor to:

• apply a first liquid polymer to a first surface of a substrate, the substrate having a second surface that is opposite the first surface;
• illuminate the first liquid polymer with light to change at least one property of the first liquid polymer and obtain a modified polymer attached to the first surface of the substrate;
• apply a second liquid polymer to at least a portion of a surface of a Fresnel structure;
• apply the second surface of the substrate having the modified polymer attached to the first surface to an outer surface of the second liquid polymer applied to the Fresnel structure to obtain a stacked Fresnel structure, the stacked Fresnel structure comprising the modified polymer placed on the first surface of the substrate, the substrate having the opposite second surface directly coupled to the outer surface of the second liquid polymer, the Fresnel structure and the second liquid polymer coupled to the Fresnel structure;
• and
• illuminate the stacked Fresnel structure with light to obtain an immersed Fresnel structure having the modified polymer on top of the immersed Fresnel structure and the Fresnel structure on bottom of the immersed Fresnel structure.

An immersed Fresnel structure comprising:

• a modified polymer positioned on top of the immersed Fresnel structure;
• a substrate having a first surface and a second surface opposite to the first surface;
• a first liquid polymer applied to the first surface of the substrate and illuminated with light to change at least one property of the first liquid polymer and obtain the modified polymer attached to the first surface of the substrate;
• a Fresnel structure positioned on bottom of the immersed Fresnel structure;
• and
• a second liquid polymer applied to at least a portion of a surface of the Fresnel structure, wherein the second surface of the substrate having the modified polymer attached to the first surface is applied to an outer surface of the second liquid polymer applied to the Fresnel structure.
