| Outline of Final Research Achievements |
We have fabricated hybrid optical devices by combining organic semiconductor crystals of thiophene/phenylene co-oligomers with optical resonators. These resonators were diffraction gratings made of aluminum-doped zinc oxide (AZO), those made of photoresist, and dielectric multilayer mirrors made of silicon and tantalum oxides. The devices showed distinct narrowed emissions under photoexcitation. We systematically observed these emissions from the devices having different crystal thicknesses and different resonator lengths, and developed an analysis technique to design the wavelength positions of narrowed emissions. We deposited hole- and electron-injection contacts on these devices and the devices showed current-injected emissions.
