| Outline of Final Research Achievements |
We studied photonic crystal microcavity for ultrahigh sensitivity sensing using terahertz wave with frequency located between the radio and light waves. We fabricated the cavity with a Q factor of approximately 10,000 in the 0.3 THz band from high resistivity silicon wafer using microfabrication technology. As a test bed for the sensing application, we successfully detected a change in the resonant spectrum of the cavity when a dielectric film with a thickness smaller than 1/100 of the wavelength was attached to the surface of the cavity.
