Outline

Our team conducts intensive research on novel photon manipulation technologies, building upon knowledge and experience gained from studies of light-wave interactions with nanometer scale fine structures. These photon manipulation technologies are intended for applications such as three-dimensional nanofabrication systems and ultra-sensitive molecular sensing devices.
Figure (a) shows a scanning electron microscope image of the RIKEN logo, composed of a nanometer scale aluminum structure that absorbs light at specific wavelengths determined by its size and shape. Figure (b) presents an optical image of the RIKEN logo under white light illumination. Figure (c) demonstrates a color palette exhibiting a wide gamut of colors.
