| Outline of Final Research Achievements |
We attempted to realize Bose condensation of exciton polaritons using organic dye nanofibers that propagate exciton polaritons. First, we developed a technique to micromanipulate nanofibers on a substrate. Using the technique, we constructed a ring resonator (Q > 4,000) by jointing the both tips of a nanofiber. To observe Bose condensation, we excited the ring resonator with an intense pulsed laser beam. Although we have not succeeded in observing the condensation till now, we found several new phenomena concerning propagation of exciton polaritons along the nanofibers. These findings will lead to novel nanophotonics technologies.
