Research Areas

Photon technology has been limited due to the diffraction of light. In Nanophotonics Laboratory, we develop the breakthrough science and technology to realize nano-manipulation of structures using photons, exceeding the classical diffraction limit. The research includes the development of theories and technologies. To manipulate (observe, fabricate, detect, analyze and control) nanostructures, near-field optics and nonlinear spectroscopy are combined. Novel device developments, in particular nano-plasmonic devices, chiral nano-photonic devices, and, left-handed nano-photonic materials are intensively investigated.

Research Subject

  1. Establishment of near-field nanophotonics and its application to linear and nonlinear spectroscopy
  2. Establishment of material nanophotonics and its applications to nano-functional photonic devices
  3. Establishment of nanoplasmonics and its applications to photonic devices
  4. Establishment of chiral nanophotonics and its applications to optoelectronics
