| Outline of Final Research Achievements |
Three-dimensional photonic chips are successfully developed based on two kinds of photonic structures, which are the metal-rod-array(MRA) and microporous-polymer-structure (MPS). The molecular sensing for liquids and gases with different dipole moments are successfully demonstrated on the 3D photonic chips. The MPS photonic chip is sensitive to the vapors of volatile-organic-compounds (VOCs) and the detectable molecular amount is down to 1 ppm for the acetone molecules. The MRA chip is sensitive to the liquids of VOCs, and the detectable molecular amount is down to 0.1 mmole for the dipole-moment difference around 0.01 Debye. Such high sensitivities of the molecular sensing based on THz photonic chips are resulted from the enhanced optical-path-length inside the chips. Based on the theory of terahertz waves interaction with the 3D photonic structures, the research additionally approves the multiple layer model of skin and obtains the frequency-dependent penetration depth in 0.1~1 THz.

| Academic Significance and Societal Importance of the Research Achievements |
The projects realize 3D printing methods in terahertz optics to guide the college students in the University of Tsukuba. The optical sensing methods are also attractive and make minute amounts of molecules visible via THz wave detection. The sensors are useful for the scientists and engineers.
