Development of Three-Dimensional Fabrication Technologies Using Laser Processing and 3D Printing for Terahertz Optics Production

Lithography techniques conventionally used to make artifical strucutres can only make quasi-two-dimensional structures. We are developing new technologies which makes it possible to produce a three-dimensional artificial structure with a resolution of several tens of micrometers smaller than the wavelength of the THz wave. In this talk, I introduce the development of three-dimensional artificial structures for THz wave control fabricated by using laser processing and 3D printing technologies
