Abstract

Our work in the fields of three-dimensional (3D) laser microfabrication and plasmonics currently taking place at Research Institute for Electronic Science (RIES) and Nanotechnology Center of Hokkaido Univ. will be presented.

We demonstrate a 3D laser microfabrication of photonic crystal templates by direct laser writing and holographic recording in SU-8 resist. Optical and structural properties of photo-polymerized structures will be presented. Current limitations and possible new applications of metal coated 3D photonic structures made by laser photo-polymerization will be overviewed.

Nano-patterns of Au, Ag, and Cu prospective for sensor applications with field intensity enhancement factors up to 104 (corresponding to the Raman enhancement factor of 108) were templated over large (sub-mm in cross-section) areas by liftoff technique. Their properties and possible applications are discussed.

We also show new emerging prospects and applications of 3D laser structured materials in micro-photonics and micro-fluidics.
