Nano-optical devices and integration based on nanopattern replications and nanolithography

We developed a nano-manufacturing platform based on wafer level nano-replication with mold and nano-pattern transfer by nano-lithography. The nano-replication process, which based on imprinting a single-layer spin-coated UV curable resist, achieved excellent nano-patterning fidelity and on-wafer uniformity with high-throughput. Nano-optic devices, such as, quarter wave plates and polarizers, were manufactured with the nano-manufacturing platform. Excellent wafer level performance and yield were achieved. The developed technology is suitable for high-throughput and low cost manufacturing needs for commercializing nano-structure based optical devices and integrated optical devices.
