Innovative Photon Manipulation Research Team intensively studies on the photon manipulation technology using knowledge and experiences obtained from the researches on light interaction with sub-wavelength fine structures. New photon manipulation technology will be applied for three-dimensional nanofabrication systems, high sensitive single molecular sensing and detection devices, and next generation ultrahigh capacity optical data storages.
