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.
