Abstract

The article gives two examples of the incorporation of liquid phase coated low refractive index (RI) and high refractive index materials in a proof-of-concept optical devices. Using ultra low RI (1.25) and ultra high RI (2.05), a 12-layer dielectric mirror is constructed. Optical properties of the stack are compared against to simulations, and a SEM-image of the stack is provided. The second example of using of high RI/low RI materials is provided where UV-curable, high RI material (1.9) nanoimprint material is nanopatterned, followed by gap-fill and protections by a cover glass using a dual cure (UV+thermal) RI 1.4 low refractive index bonding adhesive.
