Innovative Photon Manipulation Research Team
Innovative Photon Manipulation Research Team intensively studies novel photon manipulation technologies using knowledge and experiences obtained from the researches on light wave interaction with sub-wavelength fine structures. These photon manipulation technologies will be applied for three-dimensional nanofabrication systems, ultra-high sensitive molecular sensing devices, and so on. Figure (a) shows a scanning electron microscope image of RIKEN’s logo consists of a sub-wavelength aluminum structure, which absorbs light of certain wavelength determined by its size and shape. Figure (b) shows an observed image of the RIKEN’s logo under white light illumination. Figure (c) shows a demonstrated color palette covering a broad gamut of colors..
