Abstract

Conformable phase masks and transparent photopolymers provide the basis for a simple optical technique that can form complex, but well defined three dimensional (3D) nanostructures in a single exposure step. This talk describes the method, presents and range of examples of its ability to form 3D nanostructures including free standing particles with controlled shapes) and rigorous coupled-wave analysis of the associated optics. Single step, large area 3D pattern definition, sub-wavelength resolution and experimental simplicity represent features that make this method attractive for applications in photonics, biotechnology and other areas. We provide examples in passive mixers in microfluidics, bandgap structures in photonics, and reservoir targets in shockless laser compression.

Seokwoo Jeon was born in Seoul, Korea in 1975. He received his B.S. degree in 2000 and his Master degree with Professor Shinhoo Kang from Seoul National University in 2003 after one year exchange graduate student with Professor Paul V. Braun at University of Illinois at Urbana-Champaign UIUC). He is currently pursuing his Ph.D. degree in Materials Science and Engineering at UIUC under the guidance of Professor John A. Rogers. His research interests include softlithography, 3D nanopatterning, microfluidic systems, and optically functional materials & devices.
