Terahertz light receiving / emitting module and terahertz light polarization control method

摘要

Provided is a terahertz light receiving and emitting module that can freely control the in-plane polarization direction of terahertz light, and does not require module arrangement change or optical adjustment even when the in-plane polarization direction is controlled. The module (11) includes a hemispherical lens (13), an antenna element (14), a mount element (15), a fixed cover (12), and a rotary table (16). The antenna element (14) has an antenna pattern formed on the front surface and abuts against the flat surface of the hemispherical lens (13) on the back surface. The mount element (15) and the fixed cover (12) hold the antenna element (14) and the lens (13). The rotary table (16) rotatably holds a rotating body including a lens (13), an antenna element (14), a mount element (15), and a fixed cover (12).
