Terahertz wave resonators composed of three-dimensional photonic crystals composed of alumina lattices with diamond structures were designed and fabricated by using microstereolithography process. These three dimensional periodic structures of ceramics can reflect perfectly the terahertz waves through Bragg diffraction. A micro glass cell including water solvents was put between two photonic crystals to realize multiple resonations of terahertz waves to synchronize with various vibration modes of saccharide or protein molecules and control biochemical reactions through electromagnetic excitations.
