ABSTRACT:
A transmission line for propagating a terahertz wave generated based on a carrier generated in a carrier generation layer includes a first region in which the terahertz wave propagates in a first direction and a second region having a different impedance compared to the first region and forming a reflection interface with respect to a terahertz wave which propagates opposite to the first direction. The transmission line is formed so that a distance from an irradiation location at which light is irradiated to the carrier generation layer to the reflection interface is smaller than D, where D is a distance converted from a half width of a time waveform of a terahertz wave which propagates in the first direction without passing through the reflection interface. Accordingly, a terahertz wave can be made to propagate with energetic efficiency, to a direction the terahertz wave is required to propagate.
