We investigated optical characteristics of 5,5″-bis(4-biphenylyl)-2, 2′:5′,2″-terthiophene (BP3T) single crystals with naturally grown parallel edges. These crystals showed interference modulation spectra due to the Fabry-Perot resonator. From these spectra, we evaluated their resonator quality factors and the refractive index of BP3T. As a result, we obtained a high quality factor of 1700 and a high refractive index of 2.7.
