| Research Abstract |
Surface-emitting organic laser devices were fabricated by introducing DBR resonators and photonic crystals into dye-doped and π-conjugated thin films. Raman laser oscillations were obtained when the stimulated resonant Raman scattering from those polymer films was coupled with the lasing modes of those resonators. Towards future development of electrically pumped organic lasers, light-emitting field-effect transistors with ambipolar carrier characteristics were fabricated with liquid crystalline π-conjugated polymer films, and electroluminescence was successfully obtained under AC-gate operations.
