| Research Abstract |
(1) We succeeded that the enhancement of THz detection efficiency by cavity type one-dimensional photonic crystal in THz region. This is regarded as a kind of a THz pump-optical probe spectroscopy, and measurement sensitivity can be improved by a introduction of photonic crystal.(2) We fabricated one-dimensional photonic crystal in visible region using spin-coating and we observed a cavity polariton in this structure.(3) We successfully observed that narrow-band and fast THz transmittance modulation effect by optical pump-THz probe spectroscopy.
