Outline of Final Research Achievements

Single crystalline nanofibers constructed from organic dye thiacyanine propagate exciton polaritons generated by optical excitation. In this project, we demonstrated that a 90-nm-wide-nanofiber, which is much narrower than the wavelength of light, efficiently propagates exciton polaritons by tuning the dispersion curves of the polaritons by cooling. Moreover, we developed a technique to coupling near infrared light into nanofibers using the Raman scattering and investigated the propagation properties for the wavelength range. We found that thiacyanine nanofibers efficiently propagate near infrared light.
