Abstract
A photo conductive antenna irradiated with light pulse and generating terahertz wave includes a first layer formed by a semi-insulating substrate, a second layer located on the first layer and formed using a material having lower carrier mobility than carrier mobility of the semi-insulating substrate, a first electrode and a second electrode located on the second layer and applying a voltage to the first layer, a first region in which the second layer is formed on the first layer, and a second region in which the second layer is formed on the first layer, wherein the second region is located between the first electrode and the second electrode in a plan view, and the light pulse is applied to the second region.
