High refractive index materials for nanoimprinting waveguides: challenges and solutions

High refractive index resins are key enabling components for direct nanoimprinting of AR waveguides and need to meet the strict requirements across optical quality, replication pattern fidelity, mass manufacturing process stability, and long-term reliability. This talk will highlight the latest developments in Inkron’s state-of-the-art nanoimprinting materials for both spin coating and ink jet printing applications. The talk will address and present solutions for the photostability challenges of titanium dioxide based high refractive index materials, pattern fidelity changes in repeated replication processes and low temperature process requirements of emerging plastic substrates.
