| Outline of Final Research Achievements |
In order to carry out research on tunable ultrafast THz switch by hybridization of metamaterial and one-dimensional photonic crystal, we studied the following element technologies. First, a THz metamaterials such as a cut wire or an electric split ring resonator was fabricated on a semiconductor substrate, and their optical properties were evaluated. Next, broadband high intensity THz wave generation from air was carried out by dichroic laser induced plasma method. Finally, we analyzed the resonance characteristics of Fabry - Perot microcavity using wire grid and found that mode splitting occurs when metamaterial is introduced into the cavity. As a result, a useful wavelength variable type THz switch becomes possible.
