→Japanese It is possible to create new optical devices with nanoscale structures on the surfaces of their elements that artificially control the refractive index and optical anisotropy. The nanostructures are fabricated by microprocessing technology. This research aims to develop high-functionality optical nanostructure devices for information communication. １ 　Overview of research ２ 　Objectives and application fields ３ 　Research group ４ 　References Copyright 2004 (C) ATT'S corporationl all rights reserved.
