Prof Hiroaki Misawa<br />
31/01/<strong>2007</strong><br />
Hiroaki Misawa is a Professor at the Research Institute for Electronic Science at Hokkaido<br />
University and the Head of the <strong>Nanotechnology</strong> Research Center. He is a graduate of Tsukuba<br />
University, where he also completed a PhD studies at the Chemistry Department in 1984. His<br />
post doctoral research has been carried out in Tsukuba and Texas Universities. He was one of<br />
group leaders of the Microphotoconversion<br />
ERATO project of J apan Science and<br />
Technology Agency in 1988-93. From 1993<br />
he joined Department of Engineering of the<br />
University of Tokushima and was promoted<br />
to full professor in 1995. He moved to<br />
Hokkaido University in 2003.<br />
His current research interests include<br />
photochemistry, light-matter interaction,<br />
ultra-fast processes in materials, photonic<br />
crystals, and plasmonics. He has authored<br />
more than 200 papers.<br />
Abstract<br />
Micro-/Nano-Structures for Photonics<br />
Prof Neville Fletcher, Prof Misawa<br />
and Prof Jagadish<br />
Our work in the fields of three-dimensional (3D) laser microfabrication and plasmonics currently<br />
taking place at Research Institute for Electronic Science (RIES) and <strong>Nanotechnology</strong> Center of<br />
Hokkaido Univ. will be presented.<br />
We demonstrate a 3D laser microfabrication of photonic crystal templates by direct laser writing<br />
and holographic recording in SU-8 resist. Optical and structural properties of photo-polymerized<br />
structures will be presented. Current limitations and possible new applications of metal coated<br />
3D photonic structures made by laser photo-polymerization will be overviewed.<br />
Nano-patterns of Au, Ag, and Cu prospective for sensor applications with field intensity<br />
enhancement factors up to 104 (corresponding to the Raman enhancement factor of 108) were<br />
templated over large (sub-mm in cross-section) areas by liftoff technique. <strong>The</strong>ir properties and<br />
possible applications are discussed.<br />
We also show new emerging prospects and applications of 3D laser structured materials in<br />
micro-photonics and micro-fluidics.<br />
