| Research Abstract |
We have succeeded in the development of key technologies of the multi-probe spectroscopy based on near-field optics, where local area of a sample was photo-excited through an optical fiber probe having a small aperture, and the optical signal from a space a few hundreds nm apart was detected through another fiber probe. This spectroscopy enables us to visualize the recombination dynamics of elementary excitations such as carriers, excitons and plasmons in photonic materials like semiconductor nano-structures, and leads to a new tool for fundamental optical characterization.
